I went on two dates with a girl - one good and one kinda bad (at least from my perspective and I gather hers - both ended in sex though).

Anyway I asked her out on a third date and she asked me what i'm looking for atm - I said I like to let thins happen as they happen and she said she was down for 'cuddles and comfort and anything extra'.

After that it seems like she pretty much started to blank me after we've been texting almost daily between the first two dates. Then she asked if i was free today to which I said yes.

This morning she asked if she could raincheck it because she has a bunch of online training to do for her job (she did mention it before) and that she'll be busy next few days so this is one of her last times to do it.

Is she just constantly changing her mind about me or is this a legitimate excuse? What's a typical length of time between 2nd and 3rd date? (i'm mildly certain she still dates other people, a lot of her stories are about dating mishaps etc or whatever)
