TOPIC: The fuck am I doing wrong ?

Hey guys , need your advice here , something is driving me crazy lately.

I can't manage to have dates with girls who seemed down or with which I had some stuff happened (like kissing or obvious signals like her saying that she thinks I'm hot).

Two examples :

One girl is a sort of friend of mine , we kissed one night , spent the night making out , made plans to eat together at her place later.
Everytime I talked to her , she told me she was down for it , but for some reason she always had an excuse.
At one point I told her something along the ligns that it's okay we can move along , but she insisted on saying that she was still down for the dinner.
One or two times she sent me some text cheking up on me and saying that she still wanted to eat with me one of these days.
I tried (more because I had to) but same shit as before.

And now , last week I met a girl in the night , you can read it in my lay reports , eventually she blew me and we passed a real good time together.
She couldn't express more how she loved my body and how we would be boning if she was feeling better.
We snaped a bit the following day , she looked like excited at the idea of seeing me again (and was suprised I texted her).
Yesterday night , I tried to set the date up quickly.

It went like this :

Me : Hey sexy what's up ?
Her : I'm fine thank you, and you ?
Me : I'm cool , so your week went well ?
Her : Exhausting and yours ?
Me : Pretty chill , you know law school , till the exams I'm quite relaxed.
Which leaves us time to get to know each other , speaking of which , still on for saturday afternoon ?

She saw the text , didn't answer , sent her a playfull snap around 12 today "so what about those "new memories" or something , she saw it too and didn't answer.

Now my question is why the FUCK are they not answering me ?
I don't even fucking care about the date now.
I just want a clear answer you know?
I know it might seem like whining , but fuck man , it bugs me.
Why does one day , she jumps and suck my dick and the other she doesn't even answer my text?
Did I fuck up somehow?

It's not the first time a girl doesn't answer.
It's just that those two girls , well , I really liked them.
I get the principle of Sexual Availability , but what about setting up a date? It's not about being DTF , is it?

I'm open to your suggestions gentlemen.

Girls are crazy plain and simple, there could be endless reasons, onto the next one.

If you haven't noticed anything wrong I don't think it's your fault.

I had a great date with a chick from online. Everything is fine and we set up for next date. Low and behold, she flakes and ghost me. I promptly found another girl and ended up getting my dick sucked in a classroom.
There are a plethora of reasons or no reasons why girls change their mind or feel some way. Its not your job to think about that though. Just keep soldiering through until you find the girl that will give you the time of day.
(From my experience, I've dealt with the same shit as you and went through the same emotions. You'll get to used to it in time.)

Eh go talk to more girls. Hit up these girls you mentioned once in a while don't delete numbers. When I lived Cali I took a girl who lived down street from me to get some drinks and took her home the first night but she wasn't dtf. I hit her up a couple of times but she wasnt down to come straight to my place. So one day (at least several months after our 1st meet up) i was driving home and I saw a girl with a fat ass walking and i realized that it was the same girl so I chatted with her from my car and invited her to chill with me right then and there and she down. Took her home had some drinks and got the bang.
