Some background information
Hello again, and thank you for all your responses. I have mulling them over. There's a lot more to the story, which I should tell you...
We had dated, or for lack of a better term, been in a relationship for 3 and 1/2 years. We had our ups and downs, but for the most part we were intuned to each other. I had insecurities, and became very dependent on him for my happiness. My homelife was awful, and I would fight with him all the time if he couldn't make time for me when I needed him. Worse yet, I started to get the feeling that he would make more time for his friends than he did me, so that also triggered something in me. He initially asked for a "break" for at least a year so that he could spend time with his friends and focus on work. We would see each other on and off for another 2+ years, but it never went back to an official relationship. It seemed we would go in circles, where we'd have great communication, then begin to date, then we'd get physically intimate, and I would start asking to see him more and more, and he'd begin cancelling our dates, etc. I'd get upset, naturally, and we wouldend up not talking for weeks, sometimes months, until he'd apologize, or contact me.
The argument I was speaking about happened over a year ago. I suggested that we try to be friends before we became lovers. He agreed, but he said that it would be difficult since he'd have to put effort into it, and with his friends, he doesn't put effort, it just is what it is. We were discussing his new house one day and he asked me to "christan" it with him. That set me off, we argued, and he said that it was probably best to not talk for a while because we always end up at that point. This lead to a year of no contact.
Shortly after we initially broke up, I moved out on my own and realized how depressed I had been. I started therapy for my anxiety problems, joined a sports league, kept myself busy, met a lot of new people, dated a few guys, changed jobs, gone on several vacations, and can truly say that I am no longer "in love" with the ex, but, because he played a huge part in my life, and I felt that we did get along so well, I still care and love him enough to want to know that him and his family are doing OK. Which lead me to emailing him a short note telling him that I was sorry for the way things ended the last time that we spoke, and that it would be nice to hear from him sometime, anytime. He replied a week later. We bounced emails back and forth for a bit, and he sounded happy to hear from me. I asked him to see a movie, but he said he knew what kind of trouble it would lead us to. I know that he's been with someone for a year, so I told him that I respected him for that. I further asked whether it'd be best that we don't talk, but he said he still wanted to talk to me. I went on vacation for a month, and when I got back, I emailed him that question...
