Thanks for the replies. I know it's not the the most rational thing but it does bother me and I can see myself getting resentful towards her for it. She already has joked to take the kids from us at various points. Since we got married she would say things like, they can just live with me and they would probably be happier living with me than in a tiny big city apt, she asked if she could homeschool our kids and they can just live with her m-f. I've played nice. A lot. I'm just tired of always feeling like she is undermining me and crossing boundaries. It starts with mama X and then she will start using mama flat out.
My plan right now is just to refer to her as her initials to the kids.
Ugh. She tells terrible "jokes".
Honestly, I would just let her have the whole Mama X thing. Kids don't call their own mothers Mama X, your own mom could be simply Grandma. You'll still be Mom.
