am I a bad mom

recently my bd family stop reaching out...for lack context I cut my bd off bc he made my pregnacy hell he always accused me of talking to other guys even my guy friends he ruined my birthday and threatened me,emotionally abused me and manipulated me so I broke it off he wasn't to happy he cussed me out and all above...so I tried ti let him back in for our son when he was born but he would be on his phone my son head leaning to the side,he would get mad when he cried and had him back to me and when he would choke he would take his precious time trying to help him.i wabted to put my son in private school when he was olderfor better education but he said i would make my son a weirdo and soft and that kind of hurt beacuse i was a weird girl..when I started going back out wuth my friends he would get mad even tho we aren't tg he stopped seeing my son after that never xcomes ro se ehim text to ask how he's doing or call I'm doing it all by myself and it's alot..I've officially decided that I don't care anymore I can't force no one to parent..he spends more on himself and drugs more than my son...am I a bad mom for not wanting him around him anymore?
