My DHs adult BD will stop at nothing to split up our marriage. She uses her children as a tool to get her own way. She invites my DH over for a card night and gets him so drunk he is unable to return home until the next morning. She flatters him, she calls him "Dad your My Hero!"; "Dad I need Help Pleassssss?"; "Dad can you look after my kids for me", "Dad would stay overnight, I'm afraid to be alone, I neeeeeeed protection from my violent ex partner"; "Would you spend Grand Dad's week with your grandson?"; "Would you Come to Grandparents night with your grand daughter", "Oh Dad, would you spend the day with me to celebrate my birthday?", or would you come over for Dinner tonight to celebrate your birthday?", "Oh it's Father's Day today, "Happy Father's Day Dad, I have a present for you" would come over for a few drinks and I'll give you your present"; and it goes on and on and on. For every birthday of her children, for every Public Celebration, including Xmas, Easter, Mother's Day, New Years. Not to forget the number of times she keeps ringing the house for him on a daily basis. She never rings herself, she has her daughter ring or her friend to ring or her ex to ring. She will never ring herself in case I answer and when she knows her father is home, then she talks all night to him till it exhausts him so he has nothing left to talk over with me. I have tried for so long not to upset my DHs relationship with myself I have said nothing but it had been hurting for so long.

She never invites me to attend any of the above. My DH drops everything for her. I have only realised this has been happening and now it's too late to change things. I mean, that instead of finding this venting outlet sooner, I took matters into my own hands and vented out at him for his deception and neglect of us and I stopped sleeping with him. We are constantly arguing about the above and now I think he hates me.

Is this familiar to anyone else, do you have any solutions.
