Hi, need help understanding where I fucked up. Broke up with LTR of 4 years. This wasnt an healthy relationship at all and I know I shouldnt have started it in the first place. She was a plate, she was in love af, after 5 months dating she asks for exclusivity. She's crazy, divorced parents, past drug addictions, high n count. I know I should not LTR her but I was studying 24/7, no time for social life and wanted to bust a nut easily. So I LTR her, knowing she cant be trusted at all and ready to dump her when she gets annoying. I get comfortable and stay with her way too long. First 2 years went well, she's addicted to me and I treat her like shit(see her only when I want to fuck, not doing anything for her, not spending money on her but giving her some love when she behaves well). During this time she behaves well for the most part except in a couple occasions(flirting with other guys in front of me and I forgived her both times). Then she breaks up with me twice, says she needs more attention from me, I say ok and just go no contact. She comes back both times. Third year I move to another city for work(so third and fourth year it's long distance), she says she wants children soon(she's 23 and I am 25). I say no I can't do that, I want children in the future but it's way too early for me. She's disappointed but still stays with me. Fourth year she becomes colder, doesnt open up with me anymore, sex gets lower quality. In the last months I try to salvage the situation with some sweetness, I give her all my attention and try to be more beta but she stays the same. So I call her and tell her I don't like the way she is now and I'm not enjoying the relationship anymore, she starts insulting me. I give her a couple more days and she breaks up with me. Says we want different things, she wants a more serious commitment from me and start a family while I don't in the near future. I care about her but given her past I couldnt love her. I used this experience to practice outcome independence, I was 100% sure she was gonna cheat sooner or later but she didnt(or maybe she did and never told me). After the breakup we talked a couple times and she was stone cold. I dont understand why she was unresponsive to my "better" behavior in the end and why she went so cold so quickly. I dont want to get back with her, I just want to understand the situation. Anyway, why do you think she dumped me? Whant went wrong in the red pill perspective?
