Serious Need for Romantic Interactions Update

I do have a question for after a new YA gets married.
I am new so forgive me if this isn't the place to ask. But my child is finally an adult and got married in a big elaborate wedding. I had her new husband move in with her. Probably a mistake. However, I want her and her new husband to move out and get their own place but when I tried to get her to "move household" the whole family was coming too! Her dad, step mom, brother, husband and her. Is there a way for just her AND her new husband to move out with out her parents and brother?
