My fiancé gets pissed off because I cuddle with my daughter and do more than I do with his son. I have tried to invite him but he never wants to. His son never wants to listen to me and barely talks to me anyway. So my fiancé says I'm mean to him and I'm babying my daughter. But I don't think it's right to push aside what my daughter wants to do just because of his son. I feel like I'm neglecting her when I do.
What do I do?
