blocked ex/father of child(ren)

anyone coparent but have their ex blocked? my goal isn’t to keep the kids away from him but he’s absolutely traumatized me mentally & i moved back home (2 hours away) and blocked his number. there are still other ways to reach me if he tried. i’ve never kept his kids from him and don’t intend to. but i felt like i needed to move away and block him soon i could focus on myself on moving on. i’ve had to live in a DV shelter while pregnant, been cheated on, he’s punched a whole in a door and called me a whore, he rarely takes them (he had them 3.5 days in june), told me he wasn’t taking them on his days off because he “needs a life too”, i’m couch hopping with our two kids because i moved out and had nowhere to go and he said “that’s not my problem”, he brought his new girlfriend of a month around our kids after i asked him to wait 6 months. i’ve recently been having suicidal thoughts as i lost everything including a baby. i just need to heal and separate myself and i felt that was the best way but he absolutely lost it and plastered on social media that im keeping him from his kids when he just saw them yesterday and i unblocked him today after our son spiked a fever and i wanted to keep him informed because he deserves to know.
