Why have I stayed in this relationship so long? First, I have a strong belief in the vows I said I would keep. Next, as much as my wife has hurt our relationship by her holding grudges, controlling and more, to my knowledge she has not committed adultery even though we haven't had sex in 15 years. I see no indication she has seen other men. We have only one car that I use every day to go to work. And lastly is she has no skills to work and support herself and I could not put her out on the street. However, if she wanted to leave and could show me she was going to be taken care of more than I have, then she can go.
