Guys, What should I do?

I was in a situation ship. We talked for two years. We liked each other. But it got to much and I didn't know what to do. So I broke Contact. I wasn't very happy. I cried the whole night. And I kinda saw that he wasn't also very happy. He didn't like it if I talked to other guys. In our Sommer holidays I wrote to him his answers were very dry. My friends said I should give it a try because if I keep being sad it's not going to be a big help. He said he isn't interested in chatting with me. (He thinks I lost feelings for him) I said ok no prob and gave him Space. He is still very jealous and I notice sometimes smiling at me but when I talk to him or so he is very hatful and rude to me. I don't want to get rejected or something like that. I just want to keep my heart safe. But what should I do because I am not happy at all. Should I move on or talk to him
