Ok, then. Please note that I am not a vet which means I am in a similar situation to yours and therefore NO EXPERT. I can make suggestions but frankly, I'm in a mess myself so I can only tell you what the DB book says but beyond that, wait for a vet to weigh in.
GAL, try to detach (this is so much harder than it seems but it is possible), be a good dad, don't pursue, don't fight, don't fight the D, don't call to "see how she's doing" or text outside of child business. Go make friends, call old friends, take a class, find a favorite happy hour with a buddy, read a GREAT book, start a collection, follow your interests. THIS will help you seem busy, mysterious and like you're moving on... because YOU ARE MOVING ON. Fill your mind with things Un-WIFE. Hard. Yes. Impossible... seemingly so... but not really. Post, pray/meditate, take care of yourself, GAL and don't pursue.
She may express confusion, shock, even interest... just keep on doing what you're doing. It takes time. Lots of time.
