Confused

I miss my ex but I'm willing to move on but he's always in my way if you get me,and everyone thinks that me and this boy who are really good friends are talking and he's in the year above and we've been close for ages and my ex hates him cause when we were together I would always text him and he would get annoyed and my friends girls would break up with him because of me and people think we're low-key together but I don't know like I think I like him but I don't think we would work out in that way like I want to be more than friends with him but I don't know if he feels the same and I don't want to ruin what we already have you get me?so it's either my ex or him I don't know who to pick
