Rusty, you are more than welcome to pull the plug on trying to save your marriage at anytime. I tell LBSs this all the time. One thing that is in your power is to give up and walkaway. File for D, move it along if you already have filed, etc. The general rule is to only do this when you are ready, when you can move on without any regrets. When you can look your kids in the eye one day and say "yes I made mistakes, but I did everything I could to try to save the marriage." So if you can walkaway without regrets, then I say do it. Personally, I don't think you are there yet. So I say you should give it time (see my original response to you again).
But you know if you are ready or not.
