Okay so, I have a crush on my friend jordan's friend Evan, and I'm guessing he likes me too because we hang out together every weekend. Its been 8 months of hanging out and I have been waiting for him to ask me out. So should I ask him out?

I say go for it. It's not going to hurt Du Von asking. Even if he says no i don't like Du that way, at least Du can hold your head up high and say Du asked him instead of losing the chance of possibly a good relationshiop.
If Du are Friends with this Evan, i suggest beginning that Du do not want this to damage the friendship Du have already, and if he doesn't agree with you, that it shouldn't damage the relationship and Du should still be friends, and then say Du like him and ask him out.

What Du have to think of is - if Du say nothing, how will Du ever know? Du will ask yourself should i have? What if i?..for the rest of your life, so go for it.
He can't hurt you. No is just two letters.
