Advice Please!!🤕🤷🏼‍♀️💔

I fell in love with my straight best friend. Typical; you’re probably thinking, right? The thing is I have a girlfriend that I’ve had for about a couple months now and she lives kinda far. My best friend also has a boyfriend who she’s been dating for over a year now. And both my gf and bestfran knows I’m in love with my bestfran . But I feel like I get these mixed signals from my best friend that I just can’t interpret ( hand holding , play fighting, cuddling etc...). I’ve never met someone like her or felt this way about someone like the way I do for my best friend, So what should I do about this??
