Should I call/text her again?

I met a woman off of craigslist. I'm a hobby photographer and I wanted someone to model so I posted an ad. A very beautiful woman volunteered. We shot many photos, we had fun, and we even walked the beacth and talked for a bit after the shoot. I dropped her off at home because she didn't have a car. She said that she would love to shoot again. She mentioned to me that she was flying home soon to vist around Christmas. I wanted to shoot her before she left, so I asked to shoot and I also told her I'd give her a ride to the airport to, if she couldn't find one. I got too busy with work and stuff, so I didn't get a chance to shoot her before she left. She came back, she didn't tell me, but I texted her asking if she came back yet, and she replied, "yes, I got back a few days ago." We texted back and forth for a bit, and she told me that she iss off work the whole week, if I wanted to shoot. I told her that I had a lot of other shoots to do, but I'd be sure to fit her in somewhere. and I also told her that if she was bored later, I'd buy her a meal at a cool mall nearby and maybe take some random shots of her while we are there. She replied that she might have to help her friend move, but she'd let me know if anything changes. She didn't reply, so I guess she helped her friend move. That was on a Sunday. I texted her the following friday asking her if she would be interested in doing a shoot on Sunday. She didn't reply. I don't want to text nor email her again. I guess she's gone. Did I scare her off??
