I have been married for 32 years and have 2 DD’s aged 19 and 15. Older one is at uni. My relationship with DH is not good and hasn’t been for a long while. He is a very negative and angry person. Always seeing the worst outcome in everything and totally obsessed with saving money. He gets on well with older DD but him and younger Dd practically hate each other. Younger DD is difficult and always has been. She is defiant, badly underachieving at school and an absolute pain in the arse most of the time. However, because he is so negative and always down on her I over compensate so now she walks all over me and alternates between being wonderful and caring to being rude and very disrespectful. In my dreams I imagine living on my own and getting my life back instead of being stuck in the middle of their war. DD15 wants me and her to leave and live on our own. This would remove a lot of the conflict and she says she is only so horrible because she is so unhappy. If it was just the two of us she would be nice! As well as behaviour concerns she also has ocd which puts further stress in our lives. We never go out as a family. She won’t go out with her dad. She won’t let me go out and leave her ‘with him ‘ so I feel like a prisoner at times or her 24/7 personal slave. She never comes out of her room at home. All meals are ordered by texting me and then I deliver a cooked meal to her room usually followed by criticism over my shit cooking. Want to leave but how can I leave them together and if I take her with me will I just be more of her personal slave with no support. I have no family or friends I can stay with for a bit of a break so it’s either leave or stay. No trial run. When my daughter isn’t around like when she went on a 5 day school trip DH and I just about get along but I really don’t like being with such a negative person. I am 56 he is 66. Should I really give up on this and make a new life with/without my daughter. I know I don’t want things to stay as they are but getting out of a 32 year marriage is such a massive step. Any advice welcome.
