My husband said he doesn't want my mom in our house anymore

My husband does not want to be around my mom anymore because he hates her and doesn't want her in our home. My mom has done a lot of bad things that I don't like but have forgiven her for. My mom doesn't really like my husband because my husband is a felon and hates cops. Her dad was a cop. She believes my husband hates cops because he went to prison. My husband owns his actions. He went to prison 10 years ago when he was 20 because he stole his girlfriend's car high on drugs and crashed it. My husband hates cops for multiple reasons which he's explained to my mom.

When he was 8 his dad was killed in front of him. His dad was a town addict that the cops hated. When he was being talked to my a caseworker the cops were joking about how the person who killed his dad could have had a better shot. While his traumatized 8 year old is right there.

When he was 14 the cops were called because his foster father stabbed him in the head with a fork. They assessed his wound and were making jokes about it. He went to live with a different foster family when he was 16 and the dad was a cop who beat him and nobody believed him. Plus many other bad experiences my husband with cops. He has his reasons to dislike them that have nothing to do with his felony.

One thing my mom does that also bothers me is talking about how she raped my dad. She loves to laugh about it. My dad didn't want a 5th kid she talks about raping him to have my youngest sister. My dad is also dead now so I don't like her talking about that.

My mom is currently dating a 20 year old which is weird but my husband has decided he wants nothing to do with my mom because she made jokes about my husband's dead dad being an addict. So my husband said she can't come over our some anymore and he will never be around her again. She's my mom and I love her. I know she's overall not a great person. Which makes this all so conflicting. I'm not sure what to do
