What’s happening to me?!

A few months ago me and my ex bf broke up and I lost all feelings for him, before we dated we used to be best friends like we had that friendship u would kill for, he was closer to me than anybody else in my life was. While we dated he emotionally abused me and all this other shit and made me feel like shit, a few days ago he texted me and told me he still had my nudes and he didn’t know if he wanted to delete them yet until he had a girlfriend and that hit me hard, he texted me and that hurt, he ended up telling me he never lost feelings and that he misses me and I told him I have a new bf now and I’m not leaving him for him, I love the guy I’m with, but the thing is I realized that over the months I’ve been having hints come back to me like he is supposed to he in my life,my partner shares so much in common with him, fav color green, loves penguins, both sensitive, and blah, I’m realizing now I miss me and his friendship, the guy I’m talkin about his name is tom, that’s my ex, i miss our friendship so badly but ik he hurt me and idk what to do about it, i start my period in a week so this could have something to do with this but I really need y’all opinions on this please ❤️
