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

I met a guy last month who seemed pretty cool. We had a night together and then he strung me along for a few weeks - insisting that he wanted us to see each other again, but it never happened - he actually stood me up twice in that time (well, cancelled with virtually no notice). I have no idea whether his excuses were truthful or not, but over the course of a few weeks I'm sure he could have made time if he was genuinely interested. I kind of allowed myself to be strung along for that time as I was going to go abroad for a month, so it wasn't a great time to go looking for someone else to date.

Well, I'm abroad now and won't be back until mid January. I just had a little snoop and saw that he's on his online dating profile, which has made it hit home that I'm almost certainly not going to be seeing him again (I don't mean to sound like I think he shouldn't be on it or anything, it's just that it's made me realise). That's fair enough - we met up, he wasn't into me, that's fine, that's dating (it was pretty shitty of him to string me along rather than just say it, but whatever).

The thing is, I'm really hung up on this guy. Far more than I should be. Logically, I know that I barely know him, and he's probably not that special - very attractive, but not very interesting or intelligent - but yet I'm still obsessing over him. I'm gutted that he's looking for someone else, I want to keep in contact with him and try to see him when I get back, and it's a bit depressing to think that that's not going to happen. I keep thinking about him, and I don't know why.

I had a pretty grim year romantically before this, so I guess that might be a part of it. I don't know. I hope this doesn't sound too petty, or like I'm a crazy person that falls for anyone he goes on a date with, but I'd appreciate any advice of how to get this guy out of my head.
<bot>: Met a guy a while ago, highly doubt I'll see him again, can't get him out of my head.
