Please someone I need advice.

I’ve literally been in tears over this whole situation and don’t know what to do anymore.

I’ve been dating this man for a year. We are so in love and happy together. He has twin girls age 4 and I have an 8 year old daughter. He gets his girls every other week and I have my girl every week and she goes with her dad some weekends.

I have been trying so hard for my daughter to be comfortable when we go and stay with him but there’s been so many times where she wants to go home to her own bed. He loves her so much and feels like she doesn’t like him and it kills me because I know she does but she’s having a hard time dealing with change. It’s hard for her and when his twins wanna play with her or ask her to color with them she gets kind of rude and it makes me embarrassed. I know she’s dealing with it in her own way and I’ve tried to explain to her that mommy is happy and in love and wants her to be happy too and know that she is loved. It’s so hard being away from him during the week and we literally live two blocks away from eachother. I wanna stay with him during the week but my girl says she gets annoyed with the twins whining and stuff. I’m so upset right now I don’t know what to do. How have you people blended families? Is this normal behaviour?
