There's a lot more to this but I'll be brief. My husband and I were married last year after he divorced his ex, I am step mother to his children and all parents get on very well. However, he wants to go to NY to stay with his ex in laws and refers to his ex wife's brother's children as his nephews. I have no problem at all with him visiting them, I'm a little disappointed as he's made no effort to see my nephews or neices but I'm pretty sure that they are no longer really his nephews? Perhaps I'm hoping that he focuses more on his new extended family now.
