Ex advice

We were together 2 years broken up now for 3 months. I did the breakup because he wanted it he just couldn’t say it to me. He asked for space I couldn’t do that for the first month I failed, then the second month I managed a whole month no contact. Then he wouldn’t meet to exchange stuff I don’t know why but eventually we did and he was really upset. He seemed distraught about the decision. Now we’ve had a bit of contact texting and he’s not nasty to me and we didn’t have a bad breakup but I still have feelings. He’s been open with me about feeling lonely and said I don’t think wrong of you, I have no energy for anyone, my friends are dropping away from me like flies now too, no one at work speaks to me anymore, is barely here, I just spend all my time in my room on my own. I don’t think you’re bad you are still trying with me after everything that’s happened and that’s so kind of you” but yet I know he’s been out, I feel like his actions don’t match the words but he’s not a bad guy, he’s said before “I feel so lonely and isolated every day I hate my existence so much” I feel like he’s battling himself, “I’m sorry, I’m struggling is all I have no energy for anything, it isn’t a reflection of you or anythin” he didn’t say merry Xmas to me till the next day either, and I asked him recently if he wanted to go and watch a movie as friends as he said he was happy to be friends and he replied later saying I don’t think so sorry, it’s stepping over the line, I don’t mind messaging but that’s just gonna be a reminder of how things were not how they are” what does that even mean, how do I stop feeling this way I don’t have interest in any other guys but my ex
