I've been reading this thread for a while and decided to contribute.
I'm pretty much done with online dating. I'm sure there are decent guys on these sites, but it's fairly hard to find them among all the commitment-phobes, e-gigolos, weirdos and creeps. I started talking to a guy a couple of months ago. I kind of knew he was bad news, but decided to go with it and see how it works. Well, we met up. Had sex, twice. In the same night. We said we'd meet again. Now I'm not generally the type who has sex on the first date, or who has casual sex. Mistake is all I can say. Anyway, a day later I received a message from him stating that he's received some bad news and has to leave the country for a few days and wouldn't be able to meet up again. He knew I was leaving shortly afterwards for a while. Now of course I don't know if he's lying or not, but certainly seems like he wanted sex but nothing that it may bring with it. I don't want to say I feel used, because I obviously wanted the sex, too. But seeing him on the dating site daily (yes, I stalk him) makes me pretty upset. I guess I just expected at least some interest after we had sex, and it's still annoying me that he quite possibly lied because he didn't want to meet again. Makes me feel a bit worthless. We're still in touch but who knows for how long.
