The pain you are feeling at present is a terrible hurtful pain. For the short term it is most likely best for him to move out. If all that is happening at home is fighting there is no reason he would want to stay or you would want him to stay. There is so much hurt presently in you, that even if he did stay you would need some separation. He must make some choices in his own life, and only him clearly understanding the consequences of his actions will allow him to do that. Have you tried to write him a letter similiar to the PLan B letter they talk about in the web site. In writing this letter and giving it to my wife after she had moved out it took alot of weight of my shoulders, because I knew I had clearly outlined my feelings and commitment to her, what we both sttod to lose based on years of marriage while I also placed limits around how we would communicate, and what I believed was the best for the children. Having her out of the house gave me the time I needed to grieve, and start to take care of myself and the kids initially. At first I believed she held all the cards as to what the future of both of our lives was going to be, now I know I am holding my cards, while she is holding her cards. Personally I feel good about my future most of the time, because I have tried as hard as possible to let her know my committment to her, and if she chooses to not come back and work on things, that was her choice and I will not carry that burden around. Please keep posting your feeling's here as there is alot of positive people that also can help you through this.
