Of course I would stay married to my husband.
My husband’s career in the scientific field has been all these years quite isolated (well while at work anyway), scientists are a strange bunch.
However, I do get your point, a person can not work 24/7, we need a respite from the work.
Even if he left you here on Earth while he left to spend the rest of his life on Mars? You are a rare woman. God bless you.
