Nikki, Your story sounds just like mine. My H went back and forth for several months. One day he was nice and sweet and affectionate, the next day he was cold and mean. I could not take it anymore with us living under the same roof. He would say that he should leave, but then never do it. Finally one night after a fight, he said it again. I told him that if that is what he wanted then he had to do it right at that moment, not when it was convenient for him. I could not keep having this same conversation. Of course, I had feelings of guilt - that I forced him to go. But I have come to terms with that. He wanted to go, so I let him. We are actually getting along better now. I am lonely and sad at home alone, but deep down in my heart I know this is better than the way we were living. I think the time apart is the only way he is going to know if he wants to stay with me.
I am sorry that you have to go through this ordeal also. Good luck, Rachel
