Should I just leave?

My bf and I have 2 very different parenting styles. Growing up I was taught discipline and respect. He wasn’t taught either one growing up. He told me him and his brother were sent to jail in middle school for stealing and all his mom did was take their PS3 for a week. And yes they were guilty. He also said his mom smoked around them and left them to do whatever they wanted growing up. We have 2 kids together. A 4 year old and a 3 week old. I’ve told him about how I’d like our children to be raised. And he never agrees with me. I want them homeschooled and to learn discipline and respect and healthy emotional habits. He acts like he could care less about how they’re raised. He lets our daughter watch whatever she wants on TV for over an hour. I admit we did allow her to watch tv at an early age and I regret that but I told him if she’s gonna watch tv during the day it needs to be a learning show. He doesn’t believe watching tv all day affects the brain. I’m also religious and want both my children to be educated in the Word of God. My bf claims to be a believer but doesn’t teach our daughter anything or try to help her understand. On top of all of this. He’s a gamer, and he loves to talk trash to people. He’ll curse, say homophobic things, degrade people. I’m starting to notice my daughter will make fun of us or other ppl and laugh at them bc she sees her father constantly tb ppl. I’ve told him to stop but he says “I’m not gonna stop. I’ll just do it when they’re asleep but I’m not sacrificing my gaming habits.” Also just hearing the things he says like “I’ll slap you and ya momma” or “you a fa****” it’s a turn off and it makes me question who I had kids with. Like why are you like this?? Idk what to do
