Me (34f) and my ex (45m) have a 9 year old daughter, and he has weekend visitations every other week. She just told me that she has slept in dad's bed with him and his girlfriend this last weekend. He has been dating this woman for 2 months. I am extremely upset, I feel like this is hugely inappropriate. I haven't spoken to him about it yet as I am unsure of what to do.
Daughter is already sharing a bed with dad because he is currently living at his mother's in a section of the house where she also has an older male living as a tenant. Our daughter has a bedroom there but feels afraid in her room and wants to stay with dad. I am already uncomfortable with this situation but adding this new woman into their bed is too far. I am losing my mind here.
What should I do? Am I overreacting?
