My husband says he misses his home country.
My Husband recently told me he is unhappy with the lifestyle where we live. He said he misses his home country. I have expressed my willingness to relocate there, but he is afraid of disappointing myself and our children. I explain to him that our children are young enough to adjust, and that I have always been a flexible and adaptable person. How can I help, or is he just going through mid-life crisis?
I don't know how you can help any more than you are. You have told him you are willing to move.
He may be going through a midlife transition, in which case he may be somewhat dissatisfied with his life in general, and is focusing it on where you live. If that is the case, about the only thing you can do is wait it out.
