Boyfriend moved in his best friend

My boyfriend moved in his best friend last month to his apartment. We don't live together so I understand I don't really get a say but I hate his best friend. How he talks about women is degrading. He's divorced at 26 and he loves to say "I'll never wife another hoe." He refers to women as bitches and hoes all the time. My boyfriend excuses this behavior by saying he just really took the divorce hard because she was his first love. I don't know all the details of the divorce. Guess she cheated or something. But there are women in and out of my boyfriend's house because his friend is constantly sleeping with different women. I really don't like that or like girls coming in and out of my boyfriend's house. His friend is a fuck boy who fucks anything with a vagina. I know they've been friends a long time but I can't imagine being friends with this guy.
