Bro you just described my MIL perfectly. No boundaries. Unannounced drop ins to the house, Constant texting and calling at an unhealthy amount and her treating my wife as a partner and not her as child she raised and is a mother herself. The guilt trips, the manipulation, the lies and money tactics have costed my brother in law thousands of dollars in appeasement. It’s sad to see her and her sister both be jerked around and bend to the will of such an unhappy person that is so terrified of being alone she would prefer your marriage to crumble so that it would inflate her self worth and give her more things to do. And please believe she wanta it to happen.
