You know what, John? I'm over it too. And I'm never over it. But to say that she cannot see the big picture is an understatement. She has asked for the single life. Despite the fact that it is not the best that you can do for your son, it is the only thing that you can do. Let her have it. This is tearing you up inside. Let it go. Make the best life you can for yourself and your son, and next time, choose carefully when you marry.

And I would not advise offering to go in a month. She knows it exists. it is offered 4 times a year in most places. If she changes her mind, she can google it and ask YOU to go.
