Should I leave them??

I have this yaoi gc right? Most are friends that if known for a while now and the other half are people I don't even know. Anywayss, I have this friend who is a Pure douchbag even though he doesn't seem like it. I invited him to my gc and I told him "there is going to be gay/lesbian porn and shit" he said "it's fine add me in".....He hits on fucking every woman there. Including the lesbian couples. He constantly offends everyoneand is the most homophobic bitch alive. He says the "r" word to my friends and it's stressful. He's my best friend but he's honestly a huge dick to everyone and we all agree. I can't just kick him out cause that's going to break up our relationship but it seems to have come too that point. I don't know Why he thinks it's ok but he does.
