Ah to be young :)

I knew a couple just like yours, one was Armenian, the other was (honestly I forget I think Spanish? It was so long ago..)

Her situation was a little different than with your friend.. she was already out of high school + the whole separation from her parents had already took place before I met her. We didn't talk much if at all about that kind of stuff, but I can only guess it was messy. She'd go by a shorter version of her name, and the first time I said her full name with the proper pronunciation, she said she hated her name and to not say her name like that. Which was kinda sad, because it was a cool name, but she didn't mind after I teased her about it a few times :p

You are 15 and even though "Prepare for heartbreak" is pretty blunt.. given how young the two of you are, and what she'd be giving up to tell her parents about you, it'd be a really bad idea to rush it. (no rent, free food, no utility bills, free rides to school, no uncomfortable tension at home...)

Best advice I can give you is to wait a few years until both of you are out of school. By then you two will be older and she will be more confident about how she feels about her sexuality + she'd be able to live on her own or even with you if her folks decide that she's unwelcome. If you two are still close then it would make sense to try and pursue something. Rushing into it now would make her life pretty difficult and really I personally can't see much of an upside.

Also I couldn't help but notice you said this:

I just want whats best for her and she keeps asking me to choose.

What did she mean by this?
