I understand your pain. My ex-husband used to come for intercourse even when we havent spoken for a week like i am some sex worker. What I later learned is only when men are sexually satisfied they will open their ears and eyes to your frustrations. He wants sex to give you love, you want love to give sex. this is a vicious circle. One of you have to break this circle and it should be you since he is ready for divorce. So offer amazing romance,love,sex and give it 2-3 months. If he is still mean and horrible to you then think of the next steps. Pls hire some help so you are not tired always. this is very common issue and you are not alone in this.
