Bolt...I am so sorry this has happened. I understand how angry you are right now, but I have to agree with JS...you owe it to yourself and your children to keep up your DB'ing efforts. Now is the time to "drop the rope", as we like to say. Of course, it is ultimately your decision...
Things can still turn around. Read through my sitch from the beginning. My W was 2000 miles away with our kids. She told me she was done more than once and I'm pretty sure she had no intention of coming back.
