Married but living apart
My husband and I have children from previous marriages that live an hour apart.
Neither of us can move our children.
We also have a baby together.
We keep two houses and hubs travels back and forth.
It's exhausting and expensive.
This could go on for several years until the children are older.
If it is convenient for you then why worry about any thing else. But if it is really exhausting, then only the two of you could find possible solutions to your problem. You could try living together, all of you. Or shift nearby, if that is workable. Else, you could also decide about staying as a unit for a fixed number of days in a week. Solutions could be many but what really suits your situation is for you to decide on.
