What do I do??

It’s coming close to a year that I met the guy I used to talk to. To give you some background we were speaking for 5 months and everything was good. We were long distance but every time we saw each other we had sex so sex wasn’t the issue. We saw each other the night before and we almost had sex in my friends room when I told him I’d rather not out of respect. Then he went to his ex’s (he said nothing happened but I don’t know if that’s true). He came to mine the next morning and he started to have sex, mid sex he answered a call and then stopped. Then we started talking and he was saying how I’m a nice girl and there was nothing wrong with me but he can’t do the distance and he felt as though my friends had too much of an input on my relationship (which wasn’t true, he was making all the excuses under the sun). Anyways, I saw him a month later as it was my cousins bday (I met him through my cousin) and he was so cold towards me even though I did nothing wrong. Almost 7 months later and he hasn’t called me or anything but he still watches my stuff on social media. I had no closure from him at all. Recently, I’ve been having dreams about him but I don’t think about him like that as I’m speaking to someone else now. I don’t know how to get him out of my mind and it’s becoming frustrating😭
