I'm in a bit of a predicament.

So I'm a junior and have been to 3 high schools for personal reasons. At my second school I meet a guy and we ended up liking eachother but we never were an official couple. During the summer we went on dates but he started showing signs of being extremely possessive things I know far to well, he would get angry when I even mentioned another boy EVEN VIDEO GAME CHARACTERS! Anyways summer and I went to a new school so me and him would just text, I meet a guy in my P.E. class and it turned out he knew the guy I was "with" since, they are really good friends. Me and the new guy have a lot more in common and hung out more so I talked about him more. Which made the other guy man and he accused me of liking the new guy more than him, which wasn't true at all. Me and him took a break and I thought that this guy just wasn't for me he was to jealous. I haven't talked to the other guy in months but I still hang out with and we text and call everyday. I've now developed some feelings for him, but him and the other guy are still good friends. I don't want to get in the way of that. I need so adviceee.
