Wondered if I could get some advice, I know the initial response is she's just not that into me but what do I learn?

Had a date from an online dating site last week, the date went well (kiss closed) and she said she was interested in me. We started messaging each other that night to schedule the second date for the weekend and messaged everyday but then on the Friday night of the date she says she is busy but says she can come out on the Saturday or Sunday. I say which ever and she says she would prefer the Sunday as she has an assignment to do and would like to do it all day Saturday to come out Sunday. I say thats fine but is there any chance she can come out Saturday as she will have work in the morning on Sunday. She ignores this and we keep talking about other stuff and then I find out she went out with her friends on the Saturday for a while to the shops (not a night out though). I ask her on the Sunday I thought she was was going to be working all day Saturday and if she was still coming out at night and she ignores this again and we talk about other things. It gets to Sunday night and she still hasn't brought up when we are meeting and where so I ask her if shes that bothered about me considering we had been talking everyday for two weeks and she hasn't talked about meeting this weekend and she says she is and she didn't think it would bother me if we didn't go out that night because she saw me on Tinder and rearranges for Tuesday night. She then says on the Tuesday morning she doesn't think she has enough time for dating and will be busy for two weeks.

Now I obviously started looking for other girls on Friday the first time she blew me off but I still want to know what I could of done better? If a woman thinks you might be boyfriend material will she start blowing you off as a shit test? Its my only idea on the situation. Its easier just to move on but should have I pressed on in a joking way to get her out as soon as she started saying she way busy?

#1 answer, is a simple lack of interest. You got boring.
#2 answer, acting like your in a relationship after one date. That would be my guess, you seem to know a lot about what she's up to daily, after just one date. You are freaking her out Bro, stop that.

Could well be that. After the first date I tend to talk on the messaging more like I have known her for a long time since we have talked so much already in the past week two weeks but its barely noticeable, I am nit picking my own behavior. I got the feeling that if I had said I wasn't bothered about the blow off and asked to rearrange to another day (and if we did) we would have kept on talking like normal everyday but she would of ended up blowing me off the next week. Why keep talking? Woman just like to talk? I wasn't in the friend zone.
