Not TRYING to thread jack; just doing it, huh? Asshole. We'll get to your post too!
Anywho, I love my wife. Sure, she drives me up the wall sometimes. But thats what women do. They motivate us in one way or another. Some are better than others. So I'm not saying that I could not survive without my wife, but damn, I'd be pretty torn up. And I haven't been married for 11yrs to her. So maybe everyone else is saying kick her to the curb, I'm saying 11 yrs is a long time. It must've lasted that long for a reason. Obviously she's motivated you in the past to change, arguably for the better in some things.
Shit, everything we do in some kinda way if for a woman. Ok, not completely; but vaguely, yes. Money, house, cars = women. Yes, we may like those things too. But we also want a woman who appreciates us for our taste in the things we decide to buy, or our ability to buy the things that we do. Yes, I'd like a new M5 BMW. I think they're cool. But I'm not oblivious of it's ability to drop panties.
I digress... if you feel that the relationship has lasted this long only because of your willingness to change; then maybe it's not time for you to change anymore. Some of the other posters are right, you can't prevent the inevitable. Maybe it is time for a change for you both.
Again, best of luck.
