Just read your sitch Rough, sounds like you are focusing on yourself and GAL which is great. Realizing you have zero control over your w and truly letting her go is very hard but I feel is necessary if you are ever to reconcile.
I am also against a firm timeline where you tell yourself a decision must be made. However, you can set mini timelines and goals, let's say, August 1 you hope to be doing such and such and will re-evaluate where you are.
At that point you can set a new timeline and goal. Your outlook and perspective will change throughout this sitch so try not to think in certainties or pigeon-hole yourself into a place where you feel you have to make a decision.
Be the best dad and person you can be on a daily basis and check in w/ yourself periodically.
