Well, it definitely never works the first way. By that I mean, telling a girl you're into her as more than friends, and she says she doesn't feel the same but gives the "you never know what can happen" line. No, that never works

The guy sticks around for months (or years) thinking they’re getting closer, but when he tries to make a move again, she still turns him down because of how much she “values their friendship,” and then the guy comes here whining about being “friendzoned,” but he’s the one who put himself in that situation.

So when I say walk away, I’m saying that might change things, but that’s not why I’m saying to do it. Yeah, she might realize that she could lose her chance with you, but don’t count on that happening. I’m not saying stop talking to her and just wait for her to get back to you, no you need start moving on with your life, immediately. And that includes meeting and talking to other girls. If she happens to get back to you and say she’s interested and you still happen to be single at that time, then you can go for it, but if not, you’ll be better off because you’re not expecting that anyway.

The bottom line is to never wait for any girl, or let one convince you to wait for her.
