Needing advice

Just made this account bc I desperately need advice and I don’t know where to go to. I’m struggling with postpartum depression and I don’t have much help. Also posting anon bc i feel embarrassed to even post this. My I guess now ex has been doing this thing once a week for over a month. He’ll get up early in the morning, won’t say anything, and either will block me or turn his phone off. He’ll unblock me or turn his phone on after and text me and then he’ll come back (I would pick him up or he would Uber here bc he doesn’t have a car atm) he knows what he’s doing gives me a lot of pain and stress and he would always say he’s sorry and that he regrets doing it and won’t do it again but just keeps doing it. I don’t know what to do or if I should keep taking him back… we have a one month old.
