Lipp and Carl basically said it all for me.
Marriage is hard enough without going into it with these kinds of problems. Honestly, it doesn't really seem to me you like this gal all that much, and I can't really blame you. What will YOU ever be getting out of this relationship? Do you even know?
Not a hell of a lot, sounds like. This woman sounds like a classic shrew, sorry to say. She's got you so far on the defensive, I bet you haven't even had the opportunity to ask yourself this question.
Don't ever marry anyone unless you are really, really sure you want to make a lifelong commitment to that person. I promise you, even if you marry under *perfect* conditions, there WILL be times you will want to bury your wife head first in the back garden.
In this case, you might as well get your shovel and start digging now.
