Mixed emotions

I’m having mixed emotions about this baby I want the baby just really don’t want a relationship with my bf anymore. We have been together for 3 years but it’s like he isn’t changing the behaviors that isn’t good for our relationship. He drinks ALOT he used to binge drink and then go back to working hard like nothing happened. We tried to get him help but he doesn’t think his issues are that bad. When he drinks he texts other women. Which pisses me off. Now that I’m pregnant I’m second guessing EVERYTHING like is this somebody I want to have a child with. Sooooo confused. I don’t want to abort the baby but I kinda don’t want him and I don’t want to bring the baby in messed up
