AITAH for not understanding why Boyfriend of 2 years says his ideals changed

Okay so I don’t know how I’m supposed to be feeling. I met my man 2 years ago I was 20f and he was 19m I’m Christian and he’s Muslim and we immediately hit it off he’s been the best person ever to me but few months into our relationship we had a huge fight because he was immature ( he was micro cheating he sent a shirtless pic to his best friend on snap he was following porn stars and just a lot of women in his life ) he came back begging stayed outside my apartment all night and begged to take him back . I took him back and we got back into the relationship we would continue having arguments over women but we loved each other greatly his mum hated me cus I was Christian and would constantly poison him then another 2 months and he broke up with me on my birthday over religion saying we could never get married cus of religious differences (his mom came to this country) I was broken and confused as he was the one who asked me out in the first place and when I pointed out differences he said he would fight for us he just ghosted me and I was broken then he came back again and swore he would never leave me that I loved him and he loved me and what we had was special , he swore on the Quran that religion would never be a problem for us again he would grow a spine and fight for me , I believed him so I took him back again and we had a great problem less relationship for a year , he followed no women at all I didn’t ask him for it he just did he was perfect to me and I was the same to him , it was amazing and I’ve not felt like this for anybody now after a year the topic of religion came up again and he said he couldn’t compromise on the kids being Muslim I said that wasn’t what we initially decided we decided that we would let the kids pick and teach em both the religions . He said he couldn’t so I compromised on it I was fine with my kids being Muslim but he still finds fault being like our parents wouldn’t be happy my parents wouldn’t like u the only way this would work is if ure Muslim I couldn’t do that so I said that I wouldn’t change my religion for him the same way he wouldn’t for me . It’s just confusing how a man who loved me so much can switch up all of a sudden did the promises mean nothing ? I can’t bring myself to hate him I love him a lot still but he’s not willing to make any compromises for me he’s okay with it ending in-fact he’s pushing for it what do I do . I just don’t know what tto do. I don’t know how much more to compromise AITAH if I end up resenting him I just feel like it’s really unfair . He’s suddenly turned cold on me too saying he can’t show me affection since I’m not his future wife . An additional point is that we were never intimate . I’m saving myself for marriage . We would do things but not sex so is that what put him off? Idk what changed so suddenly we were so happy idk how to feel it feels like my world is falling apart . I lived with him for 2 years and he loved me so dearly. Idk how to feel .
