i didn't expect you to be 24. But whatever. If she calls/texts then respond. If not then let it go. simple as that. If she cancels on the movie night let her go. you can't go begging, that's pathetic and you won't win that way. She's most likely going to cancel and make up an excuse. It depends on how you handle that situation.
You'll eventually learn to never make plans with a girl you like. That's a fools errand
I disagree but I guess I understand where you are coming from. The problem is if you just try leave it all up to her to contact you you're gonna fuck up. Apparently the guy is supposed to text first or something idk. All this shit is confusing to me I've heard both sides. In the end it's gonna be blind luck really I think.
