AIO Bf was making sexist comments over the game to a random girl *NSFW

Earlier today, I heard my bf playing a game with a few friends and some random people, I heard a female voice in the game party, and as soon as she started talking my bf started getting hateful towards her and making weird comments, telling her to go back in the kitchen and sexual remarks like, you don’t get any dick, even if I was down bad I would never touch you… etc. I know that’s not normal to talk like that to anyone, I’m appalled that he would even speak of a woman in that manner especially when he has a girlfriend. EDIT: He told me if I don’t like what he does then don’t watch him or listen and he doesn’t give a fuck what happened. lol
