boyfriend doesn't like my best friend

Ok so long story short I've been friends with this girl for a while and I've been dating my boyfriend for a few months now. My boyfriend does not like my best friend at all. And my best friend doesn't really like my boyfriend. My best friend and I don't see eachother a lot and once she got a boyfriend she didn't really make an effort to hang out with me while I still would make an effort while I have a boyfriend. So yeah anyway he doesn't want me to be friends with her and gets mad at me for letting her "walk all over me" since now she's single again and wants to hang out all the time. I've tried talking to my boyfriend about it and telling him it's not really his business. My best friend doesn't really think my boyfriend and I have a healthy relationship but idk I guess I just needed to rant I'm stuck between both of them..
