I don't know that this is the advice you're looking for, but....Are you CONVINCED it's over? Or, are you absolutely positive that he's convinced? If you are, on either front, then maybe it is time to throw in the towel. Somebody has to believe in it. At present, you know he does not. Do you? If you don't, then I suppose it's time to move on. But if you still believe in your M, go for it. Keep DBing until the last moment. It's really up to you. Every marriage has something worth saving. The question for you is, what do you want? Is there something there to make it worth the effort for you? Define what you're fighting for. Sit down and really figure it out. Write notes. If there's a hint of anything worth saving, I say keep DBing. If nothing else, when your kids are older, you can tell them that you tried as hard as any human could.
