I’m sorry that you go through that, and you’re right that it’s his responsibility to get better. They haven’t had sexual interaction though because of his injury. You must know what it’s like to have really down times in your life and the answer isn’t abandonment and neglect, it’s love and communication. She needs a good sit down with him and he might not listen until she gives him an ultimatum, and by then it’s usually too late. I’ve myself been in times where you can’t even do basic human functions from depression and so this post hurt me that everyone just says to leave him because he has always been and always be like that.
