He should move on.
A girl knows within the first 5 minutes if she is attracted to a guy.
Low effort women are not worth the effort.
Yeah, that makes sense. I do think she is a nice girl and her passivity is her way of giving him a hint... better than ghosting IMO. Another weird scenario for him, a girl was chasing him pretty hard. He responded positively... then she ghosted him. It’s like a game for these girls. See how many men they can get interested in them, and then quickly move on to the next batch.
