My ex-boyfriend who used to be the nicest guy has turned into an evil monster. Help!

We're still in touch for some reason. We broke up last month. He slept with me and he changed and wasn't interested in talking to me. I felt that something was wrong with the relationship and I decided to end it.

But now he tells me that HE dumped ME after using me because I was dumb to give in to lust. He told me today that he wants someone more mature. He says I am immature and insecure and that he's very happy after breaking up with me. He also says that his next girlfriend will be better than me and very gorgeous. I don't know why he is talking this way to me.

He also keeps saying that he dumped me and that I was dumb to sleep with him. He also says that he found me very irritating during the time we spent.

It's hurting me so much. I cry because of him.

He was my friend before we dated so I assumed that he'll stay my friend after the break up but he has changed so much.

What should I do? We're in the same college and we have common friends so I have to deal with him.
