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

What 你 have to think of is - if 你 say nothing, how will 你 ever know? 你 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.
