<human>: Give me the gist of the text in a nutshell

She's wanted to be a boy to some degree since she was a pre-teen. She is upset/jealous that men do not have to deal with all the biological issues/burdens women have to deal with. She can't identify with most women.

This is an impossibly difficult topic to discuss with her since:

1. I don't have any type of dysphoria or dissatisfaction with my gender, so I can never fully understand her plight.

2. The things she hates about being a woman are biological and therefore permanent. 
There's a great sense of dread in her that things will never get easier.

3. She's not convinced that she could actually make the switch from female to male.

I've done everything I can think of to support her and make her feel loved exactly the way she is. I've made it clear that if she did eventually feel the need to switch, that I would support her and that I wouldn't leave on that basis alone.

My best advice at this point has been advising her to seek out others who have been in her situation.

She cries so hard over this at times and I feel helpless.
<bot>: Girlfriend and I are fighting because she wants to be a boy so she doesn't have to deal with the biological burdens of being a woman.
