WTF!!!
I am stunned you even asked that!
The answer is NONE!!!! Let me modify that. If you actually became a strong, centered man living your own life, having 100% moved on from her, because you had self respect---maybe then she would have some respect for you.
You entertaining her fantasies of reconciliation and the hoops she'd like you to jump just shows how emeshed you truly are! You showing no self respect and listening to and entertaining all her desires shows weakness and there is nothing for her to respect in that. It's a set-up for her to have her way.
She went to jail after hitting you on multiple occasions and now you are feeling flattered and considering her interest!!! Wake-Up!!!
Your idea or illusion that you have moved on is clearly denial. Your actions and thoughts clearly reflect you have not moved on, not even close. Other than emailing details about child rearing, absolute NC would serve you well. I am not sure what you are up to with your therapist but your line of questioning and thinking is not a healthy one, in my perspective. Find your balls.
