OT, I'm going to give you something to think about...when you meet someone new, how do you treat them? When you meet someone new, your expectations are at zero. Correct? Well, this is where you have to start w/your xh...both of you are not the same people you were a year or so ago, so both of you are starting on new ground, new beginnings. In many cases, you follow his/her lead and go from there. You do not raise the issue of what transpired to lead you where you are today. Listen, observe and follow their lead. Old relationship talks are not be raised unless they bring it up. There will be plenty of time to discuss those later once the dust settles from the "new" encounters, etc.
Learn to look at your xh as someone brand new. Leave the old views in the closet...both of you are brand new, changed individuals. Above all else, expectations are at zero at all times since everything and everyone is brand new!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
