While our relationship may be a little different because her other "husband" lives with us he does have his own space and she splits the time. He is only home weekends so when he is home he gets a little extra alone time with her when he is here but she is known to split the sleeping arrangements up staying with him 1 night and myself another. They sometimes get weekends all alone if I am out of town and from what I am told they enjoy that very much. I would say if it works for you it's all good. As long as everyone agrees I see no problem.
