with vegibean, "EVERYONE plays their part."
Have U ever heard, "If momma isn't happy, no one is?" Very true..
Not a man hater here, by a long shot, but going threw a few medium problems here in my own marriage and I know I played my part and he his.
Your wife is changing, maybe 4 her it is better, don't know, but she feels that she needs 2 do something. Can U meet her halfway? Please do not take this personally but, it kinda makes me think that it is all about "U." Marriage counselling is a grand ideal.
Remember, 2 never play the 'blame" game.
Stay strong.
