He wants to go

Let's him go, and he wants to go. You cannot control him. I know you still have emotion or feeling for him, and he is your family in your heart. You cannot do anything to change him. A lot of families get issues when the couples approach 40 to 50 years old. After the long time marriage, the gentleman always love the new and fresh thing outside. It is the nature of human. Some gentleman know how to control but some of them don't know how. You are not the only one. I met my exhusband when I was 20 years old at university. We have a good base of the marriage, but still we divorced. Protect your kids and yourself is the main thing you need think about now. You husband's action cannot based on your wishes and he has his own brain. Don't waste your time and energy on him anymore.
