AIO I’m thinking to cut off my friendship due to this

My close friend (5’11 and a stud body) always talk so dirty about my mom. He always sends reels about pussy and says “hope I see your mom’s one”. He even bully’s me infront of whole friend group saying “his mom is hot af”. Sometimes he goes beyond that playfully saying he doesn’t have transport back home and asked if my mom could fetch him but when I said yes, he be like “nah actually just wanna see your mom”. He even asked playfully sometimes “can she get pregnat?”. Sometimes it may be hot but it’s a bit disturbing to me if he didn’t come to college (I’ll be wondering is he with my mom bangng.) sometimes I feel should I cut him off. Because of him I started to watch these “hot friend mom bangs friend porn” to imagine him and her together but it’s a bit disturbing at times.

He even usually says casually “does your mom do…” then I’ll ask “do what” then he will say do “OF”. How in the right mind he even asks that?

I’ll reply him like “probably you’ll be the one doing it with your stud body and jerking your meat.” He agrees and says “yea and your mom gonna be my biggest fan on OF”.

He also treats me like his competition in academics. One mark higher than him in college…boom…his whole day mood is ruined. One time in high school he didn’t sort of include me in the high school party. When I confronted him he sort of just replied “we weren’t really close back then” what? It was just a year ago and I was just so pissed like he acted so close to me.
