WL, MArried or not this must really have hurt. My H told me when he first left taht he didn't want anymore kids BUT he is living with a woman who is 18yrs his junior so at some point a decision will have to be made. For now they are too set on travelling the world for it to happen but deep down I expect to find myself in your shoes sooner rather than later. I only hope I can be as magnanimous about it as you are.
