Yo I didn't read 10 pages, so I don't know if anyone's said this yet, but... there is a third option, which is don't roll over and accept her ultimatums. You need to get on top of this in terms of psychology. What you want to do is tell her you need her to sit down for a frank and rational discussion of the situation. You are legal. It is harmless. She HASN'T EVEN TRIED IT. At the VERY least, you have a huge amount of leverage for compromise in a debate. (There is a lot of leverage in insisting she try it before she deny it, so to speak) At the MOST, I would go ahead and tell her that she's being unreasonable for judging something she doesn't even know through experience. If you can get her to try it, you could turn your whole world around.
Don't take her close-minded thoughts and just accept that that's how she is. Give a shot towards opening her eyes and doing the world some good by changing a close-minded person into a more open-minded person. Talk to her about it. MORE. Talk about it. Communication can cure any ailment in a relationship. You can work it out without simply going to an ultimatum, if you both want it to work out. If she subconsciously prefers to destroy you (you never know...) then she might insist on an ultimatum... but if she is a kind and understanding person, she will work towards some form of compromise. She's presenting you with two polar options. Explore the middle ground, always. If she can't grasp the concept of exploring the middle ground, you probably don't want her around anyway. It really depends on what kind of girl you're dating...
My 2 cents.
