What you read on the other site is very true. Looking in that mirror, admitting all you have done, is the hardest thing to do. It's not just a short hurdle to get over, it is something that comes up in your life often, and without the justification, you are hit with it over and over and over like a neverending 2 x 4.
Soooo...until she faces this, she will continue to act the way she is. She may be facing this internally. I guess that's your only hope since you don't want to confront.
I worry about your plan to wait....basically, and tell me if I'm wrong, you are waiting until you have been through this so long that you can't take it anymore, and by then you won't care what she says or does, and then you leave her.
The talking...the communication.. about the way she is acting is a process. It's something that will need to be discussed, and rediscussed. I'm afraid you are going to wait and then have this ONE talk, and then if she doesn't say the right things, you leave, because by then you have basically no love left and no fight left in you.
