As many have said it's not over until you say it is.
Contrary to popular opinion, divorce is mutual. Both parties have to give up in order for the resolution to be complete. Now were not saying to get obsessive and stalkerish, but you'd be surprised how many marriages have been saved from the brink. After reading my sitch I'm sure you have seen how close I have been to the brink. Just keep plugging along and make yourself better. Close the door lock it if you must, but leave a key hidden in a spot you know he can find it.
