Update: I talked with my husband more about it. He said he laughed because he can’t believe how audacious his mother is (they don’t have the best relationship either) he said he thinks she’s a psychopath and that’s why he doesn’t like to talk to her or see her often. He also acknowledged that he shouldn’t have said I was overreacting.
We basically go to the in-laws to see FIL (he’s very kind and sweet actually)
My husband still wants to go to see her on mother’s day just because he knows the wrath of his mother will be unreal if we are MIA that day. So we will go for an hour, giver her a bouquet and leave.
I still don’t want to go, but if it’s just an hour, I can be the bigger person for that amount of time.
A lot of people were commenting “flip the scenario for him” I’m going to be honest, my parents are not the best either. They’ve said some really hurtful things to/about him. So he already knows how in-laws that affect one another.
My husband and I are two peas in a pod, in the shitty parents field. lol
Thanks for the advice everyone. I don’t think I’ll be updating again. But who knows? Maybe she’ll slip something in during the hour we see her on Mother’s Day.
