Not for myself mind you, but my girlfriend.

Here's a rough run-down of the situation:

I am an 18 year old college student in Chicago, Illinois. My girlfriend is a 15 year old high school student who identifies as a transgender. She has very thoroughly decided that later in life, she wishes to be male.

She jokingly asked her mother (to gauge reaction) if she'd be hated if she got a sex change. Her mom seriously answered that "No, I'd just not acknowledge your existance,"

Obviously, the situation is not a good one. She's told me that this is what she wants with her life, and that she'd most likely be disowned if she told her parents ANYWAY... So is there a way that she could move in with me until she was legal age? Does this sound too wrong and controversial to even be touched by court? *sighs* I hate to be all idealistic, but it seems like this is what we both really want to happen. Is there any way we could go about this?

I've also noticed that Arkansas (where my gf lives) has no laws on emancipation, so if that was the only way around it, are we just both royally screwed?
