I thought my own bad choices, which I was prepared to live with the consequences of (if you can't change your situation, change your attitude!), and stick with for life...were my own problem, but then when I realized I had subjected my children to those choices too, and the dad they had was not the dad they deserved, and there were other husbands out there who were such better role models, yes crestfallen is a great word for it.
Yeah, I relate to this. It was MY choice to take my ex back after he cheated on me early in our marriage - but it wasn't just me taking that risk that he would cheat again, I subjected my future children to that risk as well.
