Thanks OP. The questions I struggle with are (and I know I need to answer them)...

1) Do I love my S enough to deal with this for the long haul.

2) can I continue in a emotionaless marraige.

3) What is truly best for the kids...to have them witness a crappy marraige or to leave and focus on being the best dad I can.

I can't say this enough and I know you guys know this - this really sucks.
