I spent the night at a friend's house about 3 weeks ago and her brother and some of his friends were there too for a "slumber party." Her brother's friend (Tyler) and I knew each other from school before we hung out, but he had a girl friend and we never really talked. We hit it off at my friend's house and talked all night. We spent the night the next night too, and cuddled all night. He broke up with his girlfriend the next day (I know home wrecker, i feel bad about it) but they were drifing apart anyway and he hasnt liked her for a while. We've hung out the last 3 weekends and have kissed a couple times, but were not dating yet. He wants to wait a little while so his girlfriend doesn't feel used (they dated for 2 years). I feel like our relationship is moving really fast though. Too fast to turn into a real relationship, or he is just trying to instantly replace his girlfriend and start where they left off. Am i just a rebound? Is it a fling that wont last? Or could we be serious?
