Sara really nailed it on the head... your marriage and family are a choice..
I have to tell you hope that I am married to someone who is very sexual. While I do want my H, I don't want sex all the time like he does, so we try and do different things.
I don't buy this nonsense of her not being attracted to you, maybe im wrong, but im sorry, having TWO affairs in not the answer!! She should have came to you first and discussed her issues, and maybe things wouldn't have gone that far.
I hope things change for you. I wasn't trying to be harsh, but we don't always look at our spouses with stars in our eyes, that's just not real life... its about caring and loving end of story.
Good luck.

Happiness can be found, even in the darkest of times, if one only remembers to turn on the light.
