<human>: Can you succinctly summarize the text in 1-3 sentences?

I'm a 21 year old college student who joined OKCupid over spring break for the hell of it. One of my first "matches" was a pretty good looking guy who I had a lot in common with. We quickly began messaging, which led to exchanging numbers and eventually a date. Things seemed to be hit, so we texted more and went on a few dates. He was pretty much a workaholic with a job that took up most of his time, but I really didn't mind much because I'm very active on campus with multiple jobs & internships. I also wasn't looking for anything too serious right out of the gates. Anyway, I got way too drunk on our third date and we ended up having sex, which was pretty fine with me. We kept seeing each other about 1-2x a week and texted frequently, but never officially defined the relationship. After about 5 weeks of dating... BAM... he just stops talking to me. He stopped replying my texts & at first I thought maybe he was busy with work. After about a week I realized that I was dumped by someone who didn't even have the decency to *actually* dump me.

It's been a few weeks since all was said and done. I *thought* I was over him, but I still find myself wasting way too much time thinking about how things ended. At this point I don't even care that things are done, or why they're finished, but rather why he just decided to stop contacting me. I've been running over how things went and I truly don't know what I did wrong. I sent him a text asking why (weeks ago), but of course I got no reply. And any further contact I would extend would just make me appear pathetic & needy, but I just don't think I can move on until I get closure, which won't happen.
<bot>: I got dumped by method of dropping communication, by a guy who I was only seeing & sleeping with for about 5 weeks. I should be over it by now, but I'm still hurt by how things ended.
