If he wants me to leave him alone, why has he acted this way?

I was involved with someone 2 years ago, ill just say it ended badly because we’re both nonconfrontational, but he refused to tell me how he felt, just passively aggressively seemed to resent me. i was devastated, i ended up somehow getting ptsd from the situation (but idk if that was intentional or not on his part, its complicated) he betrayed my trust twice (broke his word to not give up on me/stole the money i told him to give his dad/lied to me, but i told him id forgive him if he made an effort to gain back my trust..a couple days after he told me it was something i did to change his mind. i ended up leaving without saying anything and he has been refusing to speak to me since i started trying to make amends with him. hes blocked and unblocked me on facebook 7 times between 2 profiles, sent a friend request to cancel it, liked my status so i could say something to which he responded by blocking. in person, agreed to talk to me and exchanged numbers, he then texted me telling me i destroyed everything, scum of the earth and to never contact him again or he’ll file for harassment…2 months later i was unblocked from both profiles, only messaged his main one, he ignored my month apart attempts to communicate, then finally responded telling me to get out of his life or, again, hell file charges, and called me names, just to continue ignoring me…2 months later sends me an explanation of ‘what happened between us’ which he lies about, is hellbent on me betraying his trust being the reason he won’t talk to me and goes on to say he’ll respond to one more message, but itll be my last chance FOR A WHILE.he does care about me he just learned he doesn’t need many people in his life, just real ones& says don’t be afraid to move on…then, he never responds to my next message like he said he would, so i start sending like one a week or 2 weeks seeking explanation..a month later, i left a note on his dads house, addressed to the dad apologizing for leaving without thanking him just bc of a conflict between his son and me & how grateful i was for the kindness he showed me and left my number..had nothing to do with the guy i was involved with, but then i get an angry message on facebook finally telling me his dad wants nothing to do with me either, i stand up for myself and say the reason hes treating me like he is cant be what he said because he still spoke when i lived there, and then he blocked me and has left me blocked since and it’s been many months…between then and now i did go see him in person but literally had a friend ask his permission first, he asked me if i wanted to sit down, insisted when i said no its ok,..he said he would think about being my friend, he didn’t seem to be concerned with the past, nor was i (it was 2 years ago at this point) i asked him for a good reason i should move on, he said cause hes interested in other people, i asked him if he was pursuing them, he said no and i offered to help, sincerely and he laughed and shrugged. i told him all i want is for there to be no conflict, i don’t want him to hate me and he said he doesn’t, i asked him why he didn’t like me enough to make an effort to work things out and he just shrugged, and i walked away when he was closing, and he came back up to me and said bye and gave me a hug and said talk to you later, i asked “will you?” he said hell think about it, obv i know this meant no, but since then, hes lied to my friend that he would message me, hes gone back to calling me a slurr, insinuated id do something for money, and when i asked what was wrong with him he claimed that he was being stalked for 2 years by me, which is really not true.. hes either ignored me or provoked me to message him, TO ignore me. he said he stopped caring, and then a year and a half later said he does care bout me. Basically, i’m asking if he’s a psychopath or gay or what? He wants nothing to do with me, but it never occurs to him to just tell me he doesn’t like me. (i havent done one thing to hurt him, i’ve apologized, the only reason i’ve ended up making more efforts to talk to him is when he’s responded with ambiguity and because he said ‘for a while’ which to me looks like punishment.
