<human>: The guy is a friend of a friend. He has pursued me for years, claiming I was his "dream girl," but I never was interested until recently, when he cleaned himself up and got some experience. We randomly made out one night, and since then we texted for about a month while i was away on vacation.

Lots of flirty texts and the tension built till the other night. I'm leaving for college soon and for some reason he thought this was the last night he'd see me:
We go to his house and he tells me to pick a movie, then says "it's just going to be background anyways." (Wtf). The movie hasn't started and he immediately lunges at me, trying to make out. He attempts this like 6 times over the next half hour.

I was kinda pissed but eventually we start doing everything you can do from the waist up. I had my period but he tried going down on me many times. When we were getting dressed, he took out a box of Trojan Magnums and told a bullshit irrelevant story. He definitely just wanted me to see they were magnum..

My question is: Why the sudden change in personality?? He'd always talked so highly about me/my personality/how amazing it would be if I was with him. Now that he has a real chance, why is he being such a douche?

Also: Would hooking up with him again be a mistake? Is it disgusting to let him feel the satisfaction of another night with me if I felt kind of used? (Even though he was pretty good). I'm going away to college soon, and only have a few weeks left with him here

Can you give me a shortened version of the text?
<bot>: Guy was super interested in me, but when I finally reciprocated, he started to be a jerk. Don't know if i should continue hooking up
