So there's me, DP, my 3DCs and his DD (with is 50%). He's fabulous with mine and we are great together. His DD is quiet do you never really know what she thinks but then again gives us no hassle really. Sometimes he wants to go out with his DD (13yr) on their own and it makes me feel annoyed. I guess it reinforces to me that we are actually 2 families under one roof. Or is it just pure jealousy? Anyone in a similar situation??
