Me and my partner have been together 10 years and have a 1 year old son . From the day my son was born my MIL has found any little issue and problem with anything I do she’s so dismissive and always talks over whenever I try to talk or have a normal adult conversation . It’s getting to a point where it is unbearable to even be around her but I have to for the sake of my son I don’t want him to pick up that i can’t stand is grandmother no matter how dismissive or rude she is to me . I used to have the put up and shut it mentality towards it because as my partner said ‘ that’s just what his mum is like she’s like it with her own daughter ‘ but im sick of it now . I found myself recently matching her rudeness towards me and ignoring her when she speaks over me . Can anyone relate to this i feel like talking to a brick wall when it comes to how rude and dismissive she is and may I add she is the biggest narcissistic woman I’ve ever met , any advice would be welcomed
