What is my ex-cap will do next?

I just broke up with a Cap two months ago becuz of his jealous and controlling behavior. We stayed together for 10 months and we were each other's first love. A typical Cappy, he was so sweet and loyal and I enjoyed our relationship so much at the first few months but when his love increased, his green eyed monster grew even bigger.

We had talked about it and nothing has changed. He got mad easily at me for nothing. I was so tired and stressed and decided to leave. He was fine at first but turned really mad 2 days later accusing me of talking to other guys and guys that had been following me.

It was a mess talking to him, he was cold and mean while I was sweet the whole time. He even accused me of stealing his guy friends when his friends started to chat and text me. I was actually friends with some of them before him....

I decided to give him a b-day card on his b-day and was hoping to make peace. He was surprised and seemed quite pleased. We hugged and I said we should be friends again. He nodded and I thought things were sorted out.

The thing is he still thinks I was trying to do some bad thing to hurt him, like taking his friends and I heard he was afraid I would date his friends... I told him that I never planned to steal or date his friends and he was just cold as ice.

I am an aquarius and I don't fall in love that easy. I don't mess around with guys, all I want to do is to have a social life while I was not allowed to. He never understands it.

He told me I do not qualify to be a friends for what I do but wouldn't tell me in details. He told me to see him in person but I didn't go to him becuz I am so tired of being accused of stuff that I have never done. I was so nice and trying to approach him everytime but he just being difficult and unreasonable. I told him I was planning to invite him to my b-day party but not anymore since he doesn't want to be friends.

My questions is :

I didn't do anything wrong during or afrer our relationship and I was just being an Aquarius. Will he ever realize it and come around or will hold the grudges against me even it's not my fault? I want to be friends since we go to the same school and hang with the same group..

Please advise. Thanks!
