I think it does change the interaction patterns. The WAS has no reason to have any contact with you if they don't want to. It's easier for both parties to move on, and harder for the LBS to get the attention of the WAS. From the pov of the WAS it's also easier to move to the next relationship.
Are those the kind of things you are thinking of?
By the way, it is my personal opinion that you stand a better chance of solving things if your WAS is a man. Walk away wives tend to be more mentally comitted to their decision by the time they take action. Well, that's what I think anyway.
