On the verge of a breakup

Hey everyone, (New here ) So I’ve been with my partner for the past 1.5 years. I didn’t start dating again until I felt my absolute best, and mindfully was in the right state. I then met my boyfriend. At the beginning everything was great , although he is Muslim and I am catholic we tried to make it work and discussed if there were a future how we would raise potential children and both came to an understanding. For the past few months we’ve had nothing but fights. A simple conversation turns into an argument, I don’t care to be intimate anymore (he asks and has been patient with me there ) I feel bad as I’m holding him away from his needs thinking I’ll want it. We can’t agree on anything and. Ow the difference in cultures / religions is becoming an issues. My anxiety is now at a all time high , for the first time in a long time I’m back on medication (which makes me feel sick) and he’s not around everyday just asks if the pill had made me feel better which I explain over and over again it’s not something that will work overnight. Also, every argument he breaks up with me and then we text like nothing happened and nothing ever gets solved. I feel like we both hold on to resentment
