I’m convinced

That there are tell tell signs and red flags whatever you want to call them, when the sparks run out and it’s just like you’re with a stranger who doesn’t have any interest in having anything to do with you. Basically I’ve been with this man for going on 3 years we have a child together and after the first 3 months he stopped being touchy feely stopped complimenting me and starting downing my body bad telling me how he can see weight gain and I’m like yeah I’m pregnant duh. But anyways his excuse for not wanting to be sexual any more was bc I’m pregnant and it’s weird now. Oook I went along with it. Well the baby has been out now for a while he’s about to be 2 in a few months and not much has changed. I caught his father cheating on me so many times being super flirty having sex with other ppl and everything and with me nothing he gives me noogies and pats my head and grabs my shoulder play fights me super rough never embraces me but begs me to stay with him. For what? Why what is the reason for getting on your knees crying to me then doing all of this over n over and not treating me like you actually am attracted to me. Im 100% convinced that if the girls he cheated with actually wanted him for a relationship he would actually be faithful to them and treat them right and everything. This man literally chased me for a year before I finally got with him and then he began treating me like shit and it hasn’t stopped since . My relationship is so miserable
