I'm sorry to hear that he's pushing it. Many of them "can't wait for the marriage to be over and done with". They are the ones that thing a piece of paper will create a magical new existence for them. Unfortunately, their baggage is still intact and riding in the same space ship that they are. My xh was the same way....to bad they don't realize that it's not greener on the other side...but they all discover this later on. By then you will have moved forward w/your life and the doors will open for you to experience new challenges and w/that comes new people, old friends and family.
As for kissing you....he's just nuts. There's no telling what is gone in his mind.
I sit back now and laugh about what mine said to me after the hearing at the court house which ended our marriage....but back then I thought he was nuts....now....well, I don't think it any more, I know it.
You'll get to the point of being able to look back and see just how confused and depressed he was and you'll come to realize that there was nothing you could do to save him.
For now, review the papers and go from there. We are here for you.
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.
