My husband and I separated a while ago. Now he's saying that he'll stay married because he feels like he has to honor his vows, but he doesn't want to be present in the relationship. He isn't pursuing divorce. He said that he doesn't want to have sex, hang out, or get emotionally involved. He wants the marriage to be on paper only.

Is there anything I can do to eventually have a good marriage again? He is willing to go to therapy, but he doesn't want to go together. I need some wisdom and insight.
