Oh that's great that you are going to have your daughter at home with you for a bit! My youngest daughter just got out of the Coast Guard and son in law is still in. They live cross country. I know what you are saying. It is very hard. But I am glad for you that you are going to have some one on one time with her. That will be a blessing.
I am sure they have talked things over between husband and wife and came to their own conclusion that this will work temporarily for them.
