My mum is having an innaprorate relationship with my ex husband
My mother and sister blamed me for my ex relationship breakdown....
They continue to go see her 3 years later for catch ups...it infuriates me and even tho I've told them I think it's innapropriate they claim she needs support to and they can see whoever they want
Ex is a narcissist so I'm not surprised they are pulled to her
Sorry to hear your situation
Welcome to this supportive forum.
I am sorry that your mum is seeing your ex several times a week.
I know where inlaws have kept in contact so they can keep in contact with their grandchildren.
I think there is being civil and friendly and then there is inappropriate. Maybe once a year , or send a birthday card but as you are upset by this it seems your mum is not considering your feelings.
Have you told your mum how her actions are upsetting and affecting you?
Would you consider talking to your ex about your mum?
