Any Advice?

Lol don't be friends with her because eventually you show your emotions and could reject you just look else where if you don't want to get rejected

Stop orbiting that star and find one of you own. If she ends up single later and you are as well think about it then. If you pull her away you send a very bad subliminal message that commitments are meaningless; do not be surprised if she does not honor yours one day.

Yeah, there's really nothing else you can do but move on. What happens in the future is anyone's guess but presently, she's not into you like that. :/
