I need to rant. He likes someone else

So this guy I’ve liked since the start of the school year, let’s call him E, is part of the most popular guy friend group. And basically I’ve always suspected, my friend who is also quite popular and decent looking called B, likes him. Bc she’d always go up and play him during PE, always hang around him and snap her hair tie at him to get his attention etc.

he’s never actually responded to her that much, but he’s also a quiet kid when he’s not with his friends. So basically, these days during lunch B and her friend group would always (for 2 weeks now) hang and follow them around, they’d usually all play soccer together, and even though he’d always seem the least interested to talk to them but he’s never walked away or anything.

And while me, with a pretty average popularity friend group, couldn’t do the same ever since my friends wouldn’t and it’s seem “weird”. The only times I’ve ever rlly talked to him was WITH B during PE, and that’s rarely.

I don’t know what now since it’s so obvious she likes him and it’s only a matter of time for him to like her too. And it’s also hard for me to get over a guy since I’ve liked 2 my whole life and the last one lasted for 2 years.

What do I do? Should I just let it go at this point? Or should I try to go for him and shoot my shot? If so how? Cuz I’d want to get to know him at least first and it seems a lil impossible atm.
