In my own opinion, I believe that horses rarely refuse the bridle or refuse to be caught simply because they don't want to work. There is a deeper issue, and this behavior is only a symptom, not the actual issue at hand. Horses, in my opinion, love having jobs. But the horse has to feel safe, comfortable, and be confident in the person and their abilities.
I would also agree with having her teeth checked. Maybe she has some points or rims that are bothering her. But, I wouldn't just have any old vet or dentist out to look at her. I would HIGHLY recommend that you get Spencer LaFlure, or one of his certified dentists, out to look at her. Spencer has a different approach to floating teeth, and no one else will ever touch my horse's mouth. The results I have had, along with our friends, have been amazing and immediate.

I think you are on the right track, in reference to you putting the bridle on and then taking it off. I was actually going to suggest that next lol. When people get direct lined in their thinking, meaning that we have a goal (to catch the horse, tie them up, saddle/bridle them, ride) then we sometimes get tunnel vision and this is not what horses need us to do. They need us to take our time and pay attention to EVERYTHING, like their emotions and body language. Your horse does sound very smart, and she knows that your goal is to bridle her. So now, because you have become direct lined in your thinking, she says, "Watch me interrupt that!" But this is not bad behavior. This is just her "horseonality." I know many horses who have this kind of horseonality....they are extremely smart, always plotting and thinking lol. So your job now is to be unpredictable, but in a fun and interesting way. Horses like this pick up our patterns sooo quickly, and they then come up with strategies to foil our plans. Some horses, more extreme ones with this kind of horseonality, will throw HUGE tantrums in the form of rearing, bucking, striking, bolting....it's just because they are the dominant type. Again, this is not bad behavior. You just have to learn how to deal with this type of horse and how to turn that negative output of energy into something positive and constructive, without punishing her or making her feel wrong. So by putting the bridle on and taking it off, and doing that until she is calm, you are going to blow her mind. And then, to make it even better, DON'T RIDE THAT DAY! Take her out to graze instead. Honestly, if she were my horse, I would not ride her until the bridling issue is solved. I would invest in the time to making sure she is 100% ok with me bridling her, and I would put my principles in front of my goals. That way I set myself, and my horse, up for success.
