I dont think you blew it. If you two are "together" then you have to talk it out. lay some fraim work. There is socializing, and there is flirting. Two toooooootally different things! Some guys dont know the difference when their girl is talking to antoher male. They flip at the sight of a guy being within 2 feet of you. But on the flip side, they go flirt and they act like they arent doing anything wrong. They are, and they know it, but they play dumb! Anyways, sounds like the guy likes you, but wants to have his cake and eat it too. If he is going to claim you as his chick, he cant hit on a couple others along the way. It just doesnt work that way. I would watch him when you two go out, LIKE A HAWK!! If you get that fealing, that upset fealing...... it's not jelousy, its a fealing of betrayal. People often get that confused. Anyway, IF you get that fealing, its time to lay down the law, or realize he's an idiot. Hope that helped, coming from some experience!! GL!!
