Thanks for your post.
it can be so heartbbreaking that the one person you seek love and approval from turns you away with harsh criticism.
If you feel comfortable being away from you mother , maybe you sho7ld keep those boundaries.
Your wedding is about you and if your mum will make you feel unhappy I think maybe giving her a small role if you can cope with that.
it sounds like she maybe playing games and I wonder what how her mother treated her.
If people are toxic we need to be strong and Kok after yourself.
I think everyone in this situation copes in a way that suits them. I have known people who have cut off ties with a parent they find manipulative and who makes them unhealthy.
Others may just all ow the parentnwho upsets them in a small,part of their life.
Thanks for reaching out.
