All I can say is embrace this process. The people here can help guide you through this. Your sitch is a little different than most since you had OW in your past, so some may be a little harsh on you.
I am sure W is still hurt. You have to find your empathy hat and keep it on. I wish the best for you and hope you can keep your family together.
