He's the type of person who has to experience it to see if its the right thing. I am tempted to ask him if he plans on ending the contact permanently if things between us go well or just to leave it?
I would not ask until he begins to talk about seeing you more, etc. B/c it sounds very pushy. You have ever right, no doubt about it, but it wouldn't be a good move at this time. However, there will be a come a time, if you still need assurance he will not contact OW ever, and you can tell him.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
