I've been reading a shit ton of stuff lately, and currently debating between what I should do.

But the story goes like this: Been talking to a girl, made out with her, have not escalated to sex just yet. She's currently my 'favorite' girl that I'm currently talking to. She texted me and made plans on Thursday night to watch The Flash with me (we both follow the tv series) at my place around 9 PM. Unfortunately, she canceled on me and is trying to reschedule for Monday, when she's more free saying she's busy with stuff.

I'm supposed to have an abundance mindset, I understand that girls are flakey/etc, and that's all fine. I checked her snap and it seems like she's out partying with her friends or whatever possibly drinking with guys. The thing I'm wondering about is what should I do? I've read posts saying that she's just not that into me, otherwise she wouldn't have canceled and enthusiastically try to hang. If I have an abundant mindset, then should I just easily drop her and refuse to hang out with her on Monday. Since I have other girls that I could be hanging out with. I've also read that girls will test you brutally when they're about to have sex with you. They'll do things like ignoring you, acts like she doesn't want to talk to you, etc etc. So should I just be holding frame, hang out with her on Monday, and stick around and act unbothered that I got canceled on? Wouldn't I seem like a beta fk, if I just let her cancel on me, and still agree to hanging out on her terms on Monday? Should I even say anything to seem like I'm annoyed that my plans got canceled and obviously see her snaps partying instead of hanging out with me? Since, I want to let her know in the future, it's not okay to keep doing this. Should I act anymore distant because she did this?

Overall, I'm just wondering what should I be doing. I get confused sometimes between if it doesn't seem like a girl is enthusiastic about having sex with me/hanging out, then should I just not waste my time and effort on them like I've read? Or is it a test, realize that I need to hold frame, and stick it out without acting upset/etc? I just recently got into TRP and trying to work harder on not being a bb. Thanks for reading guys.
