I’m fell in love with my best friend

So, I’ve been friends with this guy for almost a year now and I genuinely enjoy being around him.

We actually got into a fight like a few months ago and we didn’t talk for awhile, and the only reason why we did talk was because my friend was tired of hearing me complain about not talking to him.

Now the big problem is that he likes another girl. I always see them together and he always giving her those longing looks. I hate myself for having feelings for him, and I don’t know what to do.

I can’t tell anyone, because they’d tell him. But some of my friends think he likes me, since we act so touchy feely with each other, but we’re both naturally like that.

I kind of just want to avoid him, but I know I’ll miss talking to him and being with him. Overall he’s a great friend. But I know he doesn’t feel the same, and it’s hard not talking about it.

He invited me out to spend time with some friends, but the girl he likes is gonna be there. And I already said I’d go, but now I don’t want to just to avoid seeing them together.

I’ve never been in a relationship before, but I’ve never had feelings like this either. Does anyone have any advice?
