Your husbands or kids father with 'friends'

Im having trouble understanding when you get married or start a family of your own is there such things as still going out with "the friends" i dont prohibit my bf whos the father of my two little ones to do anything but its gotten to the point where i feel like he needs to cut off his friends or cut off wantin to go chill or get high with them bs. Sometimes i feel like he doesnt really act like a father or husband (we're engaged) and im having doubts who i chose to have a family with. We have recently been fighting alot n my parents dont want me to have nothing to do with him they keep putting these ideas in my head that he will never change and hes not a good father because a real father stays with his family and helps cook to feed the kids or works hard. My dad mentions all the things he did for us and how much he was there and helped my mom when they had nothing. My dad called me stupid and told me to know my worth and if i go back with him he wants nothing to do with him and wont greet him or welcome him to their house. My bf told me he was sorry for what he put me through n he regrets disrespecting my family (he had gotten into an argument with them) and that he wanted to stay with me. Im devasted because this time around things got out of hand. I want him so badly to go apologize to my mom or them but my gut is telling me he wont because he doesnt like opening up or talking and will say no or will even say everything was not my fault. He has never been one to talk especially to older adults and he comes off as a asshole when he shuts everyone out even tho that isnt him. He says the only approval he needs is from me but i dont know what to think or do..
