My crush and ex has a crush on my best friend

Faith

I need help my (girl) best friend has a boyfriend but he lives FAR away. My other (guy) best friend likes her but she has a boyfriend and I like my (guy) bestfriend. Should I try to date him, set them up, or leave them alone? Also the my (guy) bestfriend has admitted to liking her and I have admitted to liking him. I'm confused now lol.
