Let me ask you something....what have you got to lose? The worst that can happen is that she'll say "no" or "I don't think that's a good idea". She has already divorced you, so what worse could occur? Just make it casual and make sure that you aren't too heavily invested in the outcome/her reply. If she shoots you down, just say, "no problem" and don't ask her again. Proceed dating someone that actually wants to see you...same as you would with any other woman that shot you down.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
It is hard to fail, but it is worse never to have tried to succeed. Theodore Roosevelt
