This is getting on my nerves.

I met a girl some time ago and we exchanged numbers bla blah blah. We went on a date, and we had a really good time, we talked about shit ton of stuff. It wasn't just a cringy interview date where we would just ask each other short answered questions and then answer them shortly. Enough said, it was a successful date.

But after that date, she didn't even text me once, so i thought to myself "maybe she just wants me to start the convo". So I texted her and we had a small conversation, so then I told her this:

Me: BTW why don't we meet up again I had a really great time last time.
Girl: Totally! I had a really good time as well.
Me: Awesome, let's do next weekend, same place
Girl: Alright, sounds good.

Didn't seem not interested right?
when the weekend came i asked her what day she could do and what time and she answered she couldn't because of studies. I said fair enough maybe some other time. So then I expected her to write to me next to set up a new meeting because I said to her to hit me up when she could. 2 weeks went by and she didn't even text me once. I texted her:

Me: Hey what happened with our second date?
Girl: I'm sorry I've just been under a lot of stress lately with studies (she wants to go to a really good natural science school when she graduates)
Me: Oh I understand
Girl: I'll tell you this, I'll text you right when I'm done with these studies
Me: Sure sounds great.

I was starting to get annoyed
*2 weeks later*

Me: How are your studies going
Girl: I just got finished.
Me: Alright, so what about that date we were talking about
Girl: Yeah sure I can do this weekend
Me: Great.

Now is the weekend we should have met. I asked her in the morning to to tell me if she was gonna be able to meet because otherwise I would have other plans today. She answered me just now "sorry for the wait I can't"
I dont know what to do now. Should I just leave it and stop talking to her? I really don't want to because she is a great girl. But it feels like she is just trying to be nice but dont actually wanna meet.
Help me guys.

Before getting to the main details, I'd first like to point out that you seemed to be expecting her to make the first move too many times. That's your job. Making the first move like texting first is the male role in this dance. You lead the dance. Women won't lead you or else they won't feel feminine.

Also, what happened to you here is a very common occurrence and it's frustrating to most men because most men don't understand how women's feelings of attraction work.

We automatically assume that attraction works the same way for men and women. It doesn't. When we are attracted to a woman, that feeling generally doesn't change over time. If we're attracted to her, we STAY attracted to her unless she changes (e.g. puts on a ton of weight). A woman can be attracted to you one second and be completely turned off by you the very next second for almost any reason whatsoever.

The thing I hate most about "text game" is that you have absolutely zero control over a theoretically infinite number of factors that could lead her to lose interest in you.

One of the factors you DO have SOME control over, however, is time. More specifically, the time that it takes for you to escalate things. If you take too long to make something happen, she will lose interest. The attraction women feel more, often that not, has an expiration date. It sucks that she was busy but if you don't do things to keep spiking her attraction, her initial attraction will fade.

And that's what happened to you.

Keep this lesson in mind for the future and move faster next time. Remember: abundance is key so be sure to practice on many, many women. Don't worry about this failed attempt anymore.
