Play it cool, keep it brief, keep it light, no R talk, end the meeting by saying, "thanks for bringing this to me in person, and hope you have a good weekend. I got to go, got some plans. Bye!"
I agree, don't sign anything until it's been looked over by your L. I also agree you shouldn't ask him if this is really what he wants. You wouldn't want a confused man back, surely. Maybe, one day, when he has grown up, and is unconfused, then the two of you may get back together, but he is clueless right now, but that doesn't mean he's forgotten what buttons to push with you. So, be careful.
