I'm no vet, but marriages come back together even after D, so, if you feel it's worth it, then keep DB'ing until you decide you've had enough.

No-one here can make that decision for you.

FWIW, I'm worried my W is going to do the same thing to me: she's stubborn as a mule, and now that she's decided she wants to separate and D, I'm worried she'll ignore any other possible feelings, and that's my only destination.

Whatever you decide, keep making working on a better MSP, and keep being a good dad.
