Hi Nelie,
I agree with Gary, your husband is also feeling many of the feelings we patients get, especially the "homesick" feeling for our old lives. His actions are wrong and unfair to you, he is in the wrong. But be careful to go slow with putting an end to it, leave a door open for him if he manages to get through his emotional crisis. I recently had a close friend that had kind of dissapeared during my treatments come to me and confess that my cancer scared her. She said that her fear of me dying was to much for her to handle it so she put distance between herself and me. She apologized and I told her she had nothing to apologize for, we all deal with our emotions in different ways.
I hope it gets easier for you, remember, that which doesn't kill us only makes us stronger.
Love,
Minnie
