He wants me to ask him out?

my crush was talking to my best friend and he told her that he really likes me and wants to go out with me. but he said he wants me to ask him out.
why does he want me to ask????? and how do I approach him???? what do I say??????

Now now, don't be gullible. Maybe he knew you were nearby and he's going to make you ask him out so he can turn you down. I mean, who just walks up to their friend and tells them who they want to go out with?
