My ex wants to be friends!?!?!?

[Amber]

I had this really stupid boyfriend who took advantage of me and would sometimes pressure me into doing things so I broke up with him and after he got me in trouble with my mom because she found out what he wanted me to do to him I hated him so much so I unfriended him on Facebook.
I had been the one who ended it with him but he actually didn't want to.
Anyways, after that we ignored each other until the other day when he kicked me gently on the butt in the stairs at school... And now today he sent me a friend request on Facebook!!! What should I do? Should I accept? Do u think he still likes me? Pls help! And thanks!
