Between the constant trying to break us up,  bad behavior,  attitudes,  lack of any type of discipline or accountability by anyone other than ME (including BM and her NEW husband).... I'm over it.

For years, my MIL has always stuck her nose in our business, or making calls and decisions that are completely out of her lane and definitely covertly retaliates when she feels like we or mainly me has wronged her precious babies. The skids run to her to complain and she ends up doing something drastic in return like to teach us a lesson, i guess?
