I'll share a little about my sitch that may be helpful. Right now, W is full steam ahead on the D. But about 2 months ago, before she filed, she said something along the lines of "If you asked me to make a decision now, I would decide to leave". I really regret not telling her to move out then and there.
The thing is, you'll never reach a "full try". You'll always think there's one more thing you can try or do differently.
