I don't know if I can give the best advice but I feel for you. On the Divorce make sure that you tell her you understand why she feels that way but to start dating someone might not be in her best interest. This is hard to understand but she needs to be uplifted as well. Going dark can be done in this sitch. Just make sure you are the one who ends the conversation on a good note and end it when you feel it should. That is all I can think of but as I say I may not have given the best advice.
Nothing is lost if one person is willing to fight for it!
A man who never quits is never defeated! And I am not a quitter!
