do guys ask you out even if they think they have no chance?

will a guy ask you out if he likes you, even if he thinks he doesn’t have a chance with you?

There’s this guy that I like and I think may like me back but he’s not asking me out even though I’m getting all the signs.

Is it safe to say that if he liked me enough he would just go ahead and ask, even if he thought he had absolute 0% chance and could ruin our friendship?

just to add: I’m not asking him out lol I just want to know if he would ask me out if he wanted me enough. Genuinely just wanna know if guys go for girls they like even if they’re super shy
