Ok so i sit by this girl in class and we talk and all that shit...i get the feeling shes kinda into me but im not sure...were having a party sat night and i want to invite her but dont know exactly how to do it...any suggestions? I dont want her to feel like weird if she cant come or says no you know what i mean...help

Without knowing more about the situation its hard for me to help you out with exactly what to say. What I will say though is that you have to tweak your mindset a bit and stop thinking what if she says no. That is the kind of negative and AFC energy that a girl can feel. If she does say no though just don't let it effect how you act to her.

There is a girl who this happened to me with. I did some things wrong and she backed out of a date at the last minute. However, I did not let it change how I acted around her and now the attraction between us is stronger than ever. Don't show her weakness and almost act indifferent if she tells you she can't come.

Just ask her. No reason to play games and beat around the bush. You want her to come, tell her to come. But whatever you do....if she does agree....do not and I repeat do not start texting or calling her the day of your party asking if she is coming. Invite her, make sure she has your number and leave it at that.

Okay, so reading through this my thoughts are kind of scattered but I hope some of this can help.

well, what I read on most PUA material, they mostly say to not directly ask for her to come. Don't ask a question that involves a yes or no. For example, if your going somewhere to this place whatever, tell her,
"hey im going to so and so, you should come along" and so on. So maybe "hey me and my friends are gonna have a party this saturday, you should come along!". And then she'll ask what time etc... Then you respond and then it'll naturally lead to a #.

Your goal is to get her to the party and F her but this is NOT your strategy. Your strategy is to offer her benefits while reducing her fears and removing any undesirable negative "typecasts"

So you don't invite her to your party. . . You sell the party. What are her benefits? Make it impossible for her to turn it down.
