HI, Sorry that you have found yourself in the situation that brings you here. There are lots of things in your post. There a few WAW's (Walk away wives) here with differing experiences and situations to share their advice with you.
What specifically are you looking for?
Reassurance? Information?
If you have not already.. buy the Divorce Busting book and start reading that. I'd also recommend the 5 love languages, by Chapman.
Have you posted in Newcomers? that gets a lot more traffic than here, and while there are good people in both, you may want a quicker & more response than what you will get posting only here.
peace to you.
