Any jellies have relationship advice for my friend?

I have this guy friend who is a wonderful guy but is so, so lonely. He’s got a bit of a dilemma going on.

He’s REALLY into a girl who just recently broke up with a longtime boyfriend. Said ex boyfriend happens to be one of his best friends. He has no idea how, or if, to proceed.

There’s a crazy high male:female ratio here so the “fish in the sea” argument doesn’t actually apply.

He’s coming to me for advice and I feel bad because I don’t have much to offer. What say you?
