I wish everyone in their respective situations on these forums would do the same thing, stop trying to read someone's mind, it doesn't work... ever.
I'm glad to hear your wife is being nice to you, I won't say it's entirely because of how you're handling yourself lately but I think you are having a noticeable impact on your wife. This is the same woman who wanted you out of the house over a week ago.
Yup the idea is to let them go, if they want out so badly, show them the door and open it for them, she's been fighting so hard for freedom from her marriage that now when you stop resisting her wishes and actually tell her that you're ok with it and literally show her the door, she has nothing to fight against anymore. The door is literally wide open, she could go anytime and yet... she still chooses to stay for the moment because freedom apparently doesn't feel the way it was expected to feel when she originally wanted to separate from you.
Being nice to you, asking you to help her with things, looking at you, etc. Slowly moving in your direction because you aren't chasing her (which is why guys should never pursue their WAW's), you are giving her a chance to move in the direction that she feels she can move in and you aren't rushing her and at the same time, you're working hard, remaining busy, GAL'ing, taking care of your family and taking care of you and letting go of the need to defend yourself in arguments where there are no winners, defusing every fight coming your way, and all the while maintaining a great attitude of being awesome and happy, not wasting your time on crying, begging, pleading, chasing, gift buying, hoop jumping and any other wussy man crap technique that just plain does not work.
