Advice please

I’m so annoyed because my mom thinks that my boyfriend doesn’t want to be around my family. But it’s actually ME that tries to keep them apart.

I’m 28 and my bf is 30. We have been together for a few years. My mom is super judgmental and always drove my ex bf’s away. She was always mean to them. And always complained about them to me. They could always tell that she didn’t like them, and they grew distant with me.

I don’t want to happen with this relationship because he makes me so happy. He would be sad if my mom didn’t treat him right.

Any advice.??
