Sii: I'm going to pray in particular for you. I have been through this with my first wife many years ago, and it spiralled completely out of control eventually. You must learn a difficult duality, of committing completely to the support of your wife, yet realizing that your life is a separate thing from her problem. The issues of not having any control over such critical aspects of your life, and of seeking boundaries for yourself can actually lead to deepening your relationship with God, so look for that. I will pray for you.
