One night stand lead to attachement?

[Veronica]

This guy I slept with over a yr ago seems a little obsessed with me. I remember telling him I'm not like that and one night one thing led to another and well I made mistake, I never sleep with anyone unless in a relationship. But I been in a relationship for 10 mnths now and we go to same college. This guy always asks me if I'm still with him every time he sees me every weekend. I tell him yeah and I'm n love. Theres been times he's texted me to hang out I would tell him look I'm with my bf and when I'm in a relationship I don't cheat video stay commited but this guy can't seem to let me go, how come ? He always states on fb or Twitter he loves women and he's not looking for a relationship but it seems like he always stares at me at party's or between classes I don't give him attention nothing and the other day he texted me hey" I ignored him I just regret ever doing any thing with him, mind u yes I'm gorgeous girl I'm not conceited tho
