Girlfriend trained for fitness competition and has been blowing me off

So i met this girl by chance three months ago. We hit it off from the start. Both seemed to have horrible relationships in the past. She wanted a good guy that treated her well for a change. That is the kind of guy I am. I don't get run over, but give my all to someone that cares. So it was great for a month and a half. Then she started being back and forth. Awesome one day, then cold the next. SHe never has lost touch and day. About a month from her figure competition her diet got stricter. She was moody, didn't want to hang out as much, always tired. She said it wasn't me, that I am awesome and to expect it. The last week before the competition she was miserable to talk to. I backed off alot so she can focus on it, but any little text once in awhile would go unanswered. So Friday comes along and she calls me on the way down. We talk brief, I said I miss you, she said the same. Shortly after I sent her an encouraging text that even though I can't be their (her choice) my thoughts would be. She was afraid she would have to focus on me if I was down there. So it is not SUnday and after the competiton and not one word from her. My peeve is that she is a trainer and has a facebook page and clients on their as well as the rest of the world. So the whole time she would update with pictures and posts on facebook including her 3rd place finish. I have received nothing from her. Which sucks because I paid for her nails, gas, things to help her. One picture was with her coach (no big deal right? he happens to ber her ex boyfriend and now boss). So no response at all. What do you think? Chalk it up as the 10% body fat and stress has made her thoughtless and loopy and give it a couple of days to see if she bounces back to me or She just doesn't care about me and tell her to take a hike? I'm a good guy and she knows it, just wish she would give an effort back. Thanks for any suggesstions.

Let this competition thing wear down. If she really likes you she will call in the next couple of days. I know it's hard to wait when you like someone but be positive she will call.
