How far away is "home"?
If you have feelings for her and she doesn't have feelings for you, then that gonna be difficult for you. She already told you once "lets be friends."
I say meet more girls and then you will know how "special" your lady friend is after that...
I'm in the same situation with a girl I know well and she told me (after I asked her if she thought we should date), that she "didn't want to ruin our friendship" so Yah. Find a new girl and cut back on talking to her.
Or dive right in one last time and blatantly say "Do you want to date me now or not?" Then you will no 100% what the answer is! Which I think will be the same, but do it if you want to.
"You are a reflection of your friends (and lovers)"
