Why does my ex-boyfriend behave like this?

Okay, so me and my ex broke up exactly on our 2 months anni, and I know it doesnt sound like a lot of time, but for me, it was.Anyway, I winded up dumping him cause he tried cheating on me.Then a month later (one week ago) I was at a highschool football game and he saw me.He gave the occasional dirty looks, and my friend Allie, forced him to say hey to me, and when he did it was like the 'hey' of hatred. So obviously he hates me, but then why when I hug another guy he stared and wouldnt stop. He was one of my bestfriends and now he hates me, can someone give me a translation

weel.
sounds ilke someone has a gay ex.
cheaters are pretty much liars, and both suck
its a good thing you dumped him before you got hurt any worse.
the 'hey of hatred' doesnt sound very fun though. your friend probably just wasnt being to conciderate at that point. but it looks like she tried to do the right thing..
I really dont think he hates you.
no im changing that to I KNOW HE DOESNT HATE YOUU
you where bestfriends. and even though it might seeem like things are all dirty looks and hey's from hell things will get better.
bestfriends NEVER give up on eachother, and he was obviously a reaaly good friend.
I think he'll come around. you might have to wait a bit though.
feelings from two monthes dating. and yous likeing eachother since the first tme you like even met. dont go away in a month.

bestfriends(:

How do you want him to act towards you, when you dumped him? Guys dont like rejection, so hes letting you know how he feels. You dumped him, its over, he hates you, now just move on! It doesnt help to analyze him. Hes just showing you his true self!

I have changed the title of this thread to a more suitable title.

hes angry you broke up with him, so when you hug another guy he gets mad

(p.s. the only reason I dumped him, is cause he tried cheatong on me)
