Why guys do this?

He was a friend but lately over the summer things have been changing. Now I don’t know if it has to do with him getting ready to go off to college or what but -I asked him if we were still hanging out, he said “maybe later if I feel like it” -Couple of days later he asked if I would hang out with him late at night (1 am) of course I said no to late -Then he asks if I would cuddle with him

• Days pass, he talks to me but says he doesn’t want to be friends because I get mad to much -I fight to keep friendship so he asked what I would do if I saw him in the shower. Didn’t give him a good answer so he said we can’t be friends
• I call week later to apologize about getting ‘mad’ and he says were cool and we can be friends again
• I told him I wasn’t sure if we should be friends again because I feel like I cause to much drama, so he just says “ok.” I told him “bye” and he said “goodbye fallen.”

I’m so confused because we were cool just being friends and he already has chick with friends with benifits. I don’t understand why he is doing this? please help
