You keep applying the wrong reasons to the right question! The space is for YOU and the side consequence is she gets what she wants. The more you separate yourself from her emotional instability the better YOU will feel. It does sound counter-intuitive, but it works. It is a Win/Win situation.
My parents didn't raise me with a strict set of rules...there was only one real rule. If I got in serious trouble...I would end up paying the price. Of course they weren't going to be the ones dealing the price...it would be the natural consequences. I can tell you...if I had shown up with cops at the door...I would have been going to jail for the night. Just the natural consequence of my actions. They didn't force their life on me...they let me live my life and pay the prices when they needed to be paid.
There are different opinions on wearing rings. My stance is that by wearing my band represented MY commitment to the vows I took at marriage. Nothing to do with my wife or our marriage...just the vows I committed to. So it was a personal thing...not a "I am married" thing. Can it place pressure on the WAS...yes....but that is not why I wore it and I could care less what she thought about it....it was purely for ME.
Amy is a good read...so is Sandi2. Both give a very good look into the world of a WAW. I hate that they both get attacked a lot on the board because their insight is massive.
