He was good the first week because he didn't know what kind of a handler you were, and he was just doing what he's been trained to do. If you've missed his subtle 'tests' along the way, he's figuring out that he's got your number, and he doesn't really have to be on his best behaviour. If he doesn't have much respect for you, he'll keep acting like this, and he'll get worse over time if you don't get a handle on it.
I grew up around horses, and have had my own horses for the past 7 years. I've never had to deal with a horse ever acting this way. He's been a little skiddish from the beginning. I figure after what he had been through the prior weeks it was best to allow him to adjust to yet another new place. At first he wouldn't come near his food until I backed away from it. Then I would stay, and even keep my hand on the bowl, and he would come over and eat despite me being that close. I had gotten a mare that was unsure when I first got her, but after brushing her and just spending time with her, she improved alot. This one doesn't freak out, or turn his hind quarters toward me. He simply avoids me getting anywhere close to him unless I have a treat for him. And if I manage to give him a treat I have to try to sneak my hand up to get his halter.
