Okay, so maybe there's a reason why women should just use investment bankers for expensive meals: It seems that they can be really awful boyfriends. For instance, there's the J.P. Morgan banker who cheated on his wife with a co-worker, only to follow the co-worker to London and stalk her. And then there's this alleged email from an investment banker who went on ONE date with a woman, "I’m disappointed in you. I’m disappointed that I haven’t gotten a response to my voicemail and text messages... I suggest that you make a sincere apology to me for giving me mixed signals. I feel led on by you."

In the stalking case, David Gray was convicted of harassing Daniela Rausnitz, whom he met while working in the NYC office of JP Morgan. She claims that she went to the London office to avoid Gray, himself married to a lawyer, who "deluged her with hundreds of texts, emails and phone calls as he repeatedly flew across the Atlantic to pursue her when their one-year relationship turned sour," according to the Daily Mail, which also reports:

Gray used his old key to get into her Chelsea flat, falsely said his sister had died and even claimed he was critically ill in a desperate effort to attract her attention.
His victim told police he planted a tracking device in her phone and hacked her email, leaving her afraid that his campaign would never end.
When officers confronted him at a Park Lane Hotel where she was hiding with her family he told them he was an agent for the Israeli secret service.
Even on the eve of his trial Gray was accused of breaching his bail by turning up at the same Notting Hill restaurant as his former lover.

Gray's lawyer said

, "He was a lovelorn fool, but it wasn’t criminal behavior. The problem was the last few days in August. He felt she had placed him on a pedestal and then kicked it from underneath him, so he reacted." Gray was released on conditional discharge and could be arrested if he's found near Rausnitz.

As for the alleged email from a "spurned" i-banker, a Redditor explains, "Backstory—friend couldn’t make it to philharmonic at last minute so I went alone, met this guy, went on ONE, HORRIFIC date. Then got this."

Hi Lauren,
I’m disappointed in you. I’m disappointed that I haven’t gotten a response to my voicemail and text messages.
FYI, I suggest that you keep in mind that emails sound more impersonal, harsher, and are easier to misinterpret than in-person or phone communication. After all, people can't see someone's body language or tone of voice in an email. I'm not trying to be harsh, patronizing, or insulting in this email. I'm honest and direct by nature, and I'm going to be that way in this email. By the way, I did a google search, so that’s how I came across your email.
I assume that you no longer want to go out with me. (If you do want to go out with me, then you should let me know.) I suggest that you make a sincere apology to me for giving me mixed signals. I feel led on by you.
Things that happened during our date include, but are not limited to, the following:
-You played with your hair a lot. A woman playing with her hair is a common sign of flirtation. You can even do a google search on it. When a woman plays with her hair, she is preening. I've never had a date where a woman played with her hair as much as you did. In addition, it didn't look like you were playing with your hair out of nervousness.
-We had lots of eye contact during our date. On a per-minute basis, I've never had as much eye contact during a date as I did with you.
-You said, "It was nice to meet you." at the end of our date. A woman could say this statement as a way to show that she isn't interested in seeing a man again or she could mean what she said--that it was nice to meet you. The statement, by itself, is inconclusive.
-We had a nice conversation over dinner. I don't think I'm being delusional in saying this statement.
In my opinion, leading someone on (i.e., giving mixed signals) is impolite and immature. It’s bad to do that.
Normally, I would not be asking for information if a woman and I don't go out again after a first date. However, in our case, I'm curious because I think our date went well and that there is a lot of potential for a serious relationship. Of course, it's difficult to predict what would happen, but I think there is a lot of potential for a serious relationship developing between us one day (or least there was before your non-response to my voicemail and text messages).
I think we should go out on a second date. In my opinion, our first date was good enough to lead to a second date.
Why am I writing you? Well, hopefully, we will go out again. Even if we don't, I gain utility from expressing my thoughts to you. In addition, even if you don't want to go out again, I would like to get feedback as to why you wouldn't want to go again. Normally, I wouldn't ask a woman for this type of feedback after a first date, but this is an exception given I think we have a lot of potential.
If you don't want to go again, then apparently you didn't think our first date was good enough to lead to a second date. Dating or a relationship is not a Hollywood movie. It’s good to keep that in mind. In general, I thought the date went well and was expecting that we would go out on a second date.
If you're not interested in going out again, then I would have preferred if you hadn't given those mixed signals. I feel led on. We have a number of things in common. I’ll name a few things: First, we’ve both very intelligent. Second, we both like classical music so much that we go to classical music performances by ourselves. In fact, the number one interest that I would want to have in common with a woman with whom I’m in a relationship is a liking of classical music. I wouldn’t be seriously involved with a woman if she didn’t like classical music. You said that you're planning to go the NY Philharmonic more often in the future. As I said, I go to the NY Philharmonic often. You're very busy. It would be very convenient for you to date me because we have the same interests. We already go to classical music performances by ourselves. If we go to classical music performances together, it wouldn't take any significant additional time on your part. According to the internet, you’re 33 or 32, so, at least from my point of view, we’re a good match in terms of age. I could name more things that we have in common, but I’ll stop here. I don’t understand why you apparently don’t want to go out with me again. We have numerous things in common. I assume that you find me physically attractive. If you didn’t find me physically attractive, then it would have been irrational for you to go out with me in the first place. After all, our first date was not a blind date. You already knew what I looked like before our date. Perhaps, you’re unimpressed that I manage my family’s investments and my own investments. Perhaps, you don’t think I have a “real” job. Well, I’ve done very well as an investment manager. I’ve made my parents several millions of dollars. That’s real money. That’s not monopoly money. In my opinion, if I make real money, it’s a real job. Donald Trump’s children work for his company. Do they have “real” jobs? I think so. George Soros’s sons help manage their family investments. Do they have “real” jobs? I think so. In addition, I’m both a right-brain and left-brain man, given that I’m both an investment manager and a philosopher/writer. That’s a unique characteristic; most people aren’t like that. I’ve never been as disappointed and sad about having difficulty about getting a second date as I am with you. I've gone out with a lot of women in my life. (FYI, I'm not a serial dater. Sometimes, I've only gone out with a woman for one date.) People don’t grow on trees. I hope you appreciate the potential we have.
Am I sensitive person? Sure, I am. I think it's better to be sensitive than to be insensitive. There are too many impolite, insensitive people in the world.
I suggest that we continue to go out and see what happens. Needless to say, I find you less appealing now (given that you haven’t returned my messages) than I did at our first date. However, I would be willing to go out with you again. I’m open minded and flexible and am willing to give you the benefit of the doubt. I wish you would give me the benefit of the doubt too. If you don't want to go out again, in my opinion, you would be making a big mistake, perhaps one of the biggest mistakes in your life. If you don’t want to go out again, then you should have called to tell me so. Even sending a text message would have been better than nothing. In my opinion, not responding to my messages is impolite, immature, passive aggressive, and cowardly. I spent time, effort, and money meeting you for dinner. Getting back to me in response to my messages would have been a reasonable thing for you to do. In addition, you arrived about 30 minutes late for our date. I’m sure you wouldn’t like it if a man showed up thirty minutes late for a first date with you.
If you're concerned that you will hurt my feelings by providing specific information about why you don't want to go with me again, well, my feeling are already hurt. I'm sad and disappointed about this situation. If you give information, at least I can understand the situation better. I might even learn something that is beneficial.
If you don't want to go out again, that I request that you call me and make a sincere apology for leading me on (i.e., giving me mixed signals). In my opinion, you shouldn't act that way toward a man and then not go out with him again. It’s bad to play with your hair so much and make so much eye contact if you’re not interested in going out with me again. I have tried to write this email well, but it's not perfect. Again, I'm not trying to be harsh, insulting, patronizing, etc. I'm disappointed, sad, etc. I would like to talk to you on the phone. I hope you will call me back at xxx-xxx-xxxx> (if it’s inconvenient for you to talk on the phone when you read this email, you can let me know via email that you are willing to talk on the phone and I’ll call you). If you get my voicemail, you can a leave a message and
I can call you back. Even if you don't want to go out again, I would appreciate it if you give me the courtesy of calling me and talking to me. Yes, you might say things that hurt me, but my feelings are already hurt. Sending me an email response (instead of talking on the phone) would better than no response at all, but I think it would be better to talk on the phone. Email communication has too much potential for misinterpretation, etc.
Best, Mike
