Who isn't her biological father but someone she called daddy for just over a year?
Quick fill in, me and her actual father broke up because he was a useless twat. Twat being a nice word. Anyway, I met my now ex when she was almost a year old, and he adored her, I thought we were forever and allowed her to call him daddy, he was fine with this. We broke up through my own fault (I cheated, massive mistake, feel free to flame me for it) I felt so guilty, I told him, and subsequently he left. Has not seen me or DD since, and as far as I know hasn'y wanted to see DD as a letter he left said it would hurt him too much.
Now, me and new DP, who I am not allowing her to call dad or daddy etc, were invited to go away with my family on a holiday, only to then be asked if we wouldn't mind going on a separate holiday as they have invited my ex, and want to take DD with them on their holiday. They claim, as they are still friendly with ex, that it would be good for her as he'll be at other occasions (they invited him for xmas dinner last year too) if she sees him and can stop calling him dad. She is 3 years old, and I feel she would forget about him anyway. Am I wrong not to let her go?
Everyone else says i'm right not too, but family seem to think I am being unreasonable. Any wise words from MNers?
