Annnnnd I think I just developed a crush

So for the last several months I’ve been loving not having a crush.

But as of like 30 seconds ago I think I just got one on my friends best guy friend. I should probably say that he has been in love with my friend for idek how many years and she doesn’t feel the same and makes it clear, yet he’s always PDA with her. I only hang with him when I hangout with her. Wow... this is already sucking.

But he’s really cute and nice so that’s cool. I guess I don’t know that much about him cuz my friend is the one that talks to him most, obviously haha. So before this crush gets any worse, should I just turn around and run the other way or should I go for it?
