Can I cuss her out now?? Update

My mother in law drives me crazy. If I’m not kissing her sons ass she claims I’m being rude. I was talking with my fiancé about concerts. He told me he’s never been to one so i was like “what?! You need to go see your favorite artist live” Then his Mom butt in to say “can you guys ever have a Normal conversation. It’s always you being mean to him”

Then I just looked at him in shock waiting on him to say something to her but he never did. I’m just so sick of her over reacting to everything I say

Edit to add: he’s in no way a mamma boy but even though he’s 30 she for some reason still treats him like a baby. And it wasn’t because they didn’t have money growing up. He’s 30 and has had a very good job since 21.
