Do NOT marry her if this continues. Period. I don't care how much you love her. It will only get worse, and if you have kids... you are REALLY stuck.
Everyone here will tell you the same thing.
If you have set a date, I would call it off and tell her that until the issue is resolved, no more dates will be set. Give her six months to make up her mind, and another year on top of that to prove to you that she actually means what she says, before you EVER walk down that aisle.
I know this sounds really harsh, but what she is doing to you is no less harsh.
I think you should order a copy of No More Mr. Nice Guy and do the exercises, too.
