My ex broke up with me about 2 months ago and i don't get why he did.
He said he didn't luv me, but after a few days he said he luved me and always did. So the reason he broke up with me isn't clear. I thought it was for the best and tried to forget him and we were just friends, but he did ask me to tell him if i luved him again and i didn't at first but i did after a month. When i told him he was really happy,but he acts as though we're just friends..when we really "were" friends,he treated me
as though i were more than that. i don't get what why he's acting like this. what i should do?

Ask him. He should know best.

me are confusing and puzzling creatures.
lets leave it at that.

I don't think you can stop loving someone, then just love him again. I believe love doesn't stop, nor be interrupted - no matter what. I know this from experience. So I dunno. do what you want.
