im not crazy am i

so i had a bf of two and a half years and recently we broke up about two months ago. i broke up with him when he was locked up for something. he was locked up for at least 6 months. and i left him before he got out a month later. but anyways let me give tell u guys how our relationship was. i was getting cheated on our whole relationship pretty much, he stopped two months before he got locked up. our whole relationship i felt like he didnt love me or didnt care uk. but i was stupid and thought he would change for me. every time i tried to leave he would say the right thing or i would give in like always. its a lot that he has done to me, so when i left i left for good bc i knew there wouldnt be a way for him to get me back. i ended up just talking to this guy just like a vibe type thing you know. he got out a like two weeks ago i think and he got a whole new gf, they act in love and everything and maybe they are idk but when he got out he tried wit me but i didnt want to so he moved on right away. the way he is i dont believe he really likes her but he said he “changed” but i just don’t believe he really did for the way he was talking to me when he got out. he acts like a kid and i really mean a kid bc and does stuff just to make me mad. anyways for FOR NOW he is treating her better than what he did me, im talking taking her out to eat, already meet his family, stayin the night and everything. never took me out to eat, i didnt meet his family until one year, i stayed the night but thats about it. yes he did treat me some what good in the beginning but his true colors showed later. anyways let me get where i wanted to. i moved on, yes i still care and i still got that love for him uk but its like im jealous bc he is treating her better than he did me and they only known each other for like a week. im jealous bc he told me she isnt me so he wont cheat, everything is my fault, its my fault i stayed as he did everything he did, im a stupid bitch bc i left him at his lowest and left him in their alone with nobody blah blah blah, said everything he could to hurt me more bc i didnt wanna get back wit him. ik it was wrong for me to leave him in jail but only for a month and ik thats hard for someone but im not in the wrong for anything right? im not wrong for being a little jealous he treating her better? im not wrong for leaving him? there is so much more stuff that happened to me in that relationship thats why i know me leaving was the best and im so happy i did.
