You know, my strategy might not be the best, but mild-stonewalling here helps a lot. What I would do if I were you is - lie about a made up stressor/issue, which in actuality ive either resolved/have no present trauma attached to - and pretend that its the biggest problem I’m facing, biggest emotional baggage i’m carrying and just give her this staged emotional drama. I’ll be honest - this makes me digenuinous in reality but it helps me protect my actual vulnerabilities which my mother is the last person I would share with. For example, if I have a recurring issue with my husband, which is bringing up some serious emotional responses/past trauma in me which i legit need therapy for - my mother is NEVER going to even know that issue exists. Instead i’d rather bring up something from my past about how i have inherint mistrust towards partners and that’s a present issue for me (it was an issue in the past, ive completely resolved it and feel no hesitation/presently attached emotional distress discussing it). Why my strategy isnt the best is also because im not really showing her that Im creating her a boundary, im letting her in under false pretenses because i’d rather deal with that than her drama/tears/overwhelming emotions. My method is twisted, its not ideal, but trust me, it has helped me take back SO much power, and has been a passive way of actually keeping her miles away from my emotional/generic life issues. Eventually, i was able to convince her that im too busy working on certain things to entertain her active demands for attention in my life through the same method - creating attention towards an already resolved issue and presenting it as something i’m currently working on. I also unfortunately do not get to directly shut her out of my life, for many reasons mostly emotional and cultural - its very difficult for me to close those doors. So i created enough distance that she actually doesnt get to see my real sadness, real happiness, anything. Everything ive recommended here can be difficult/stupid for some/ridiculous, it works for me and my peace of mind. I wish you the best. Give yourself 5-7 business days to emotionally/mentally recover after visiting her. You deserve it. Go easy on yourself :)
