update: i didn't get the happy mouth bit since i needed one today to work with nugget. i bought the Dee ring snaffle bit and molasses.
Today, I tied him up securely in the indoor arena away from all the other horses being tacked up on the porch and away from all the people and commotion. I gave him treats and molasses from my hand. He loved the molasses and was licking it off my hand. i then put the bit in my hand with the molasses and he started licking the bit. Then I was petting his head and muzzle and just stuck my finger in the side of his mouth. Well he freaked again!!! He pulled back and when he realized he was tied, he really freaked and pulled the post out of the ground.

I got him calmed down and he was shaking. I then walked him around the barn several times and just hung out with him. I made my husband and cousin leave while I worked with him again in the arena.
I didn't tie him up this time because when he jerked from my finger before, it freaked him out I think because he was tied. I closed the door to the arena and was in there by myself with him untied. I used the molasses again and let him lick my hands. I massaged him down a little to get him to relax. I brought my finger to his mouth again. he freaked a little but nothing like he did before. I made him give his head and he bowed it down beside of me being submissive. I tried again to put my finger in the side of his mouth and he let me. I immediately took it out and gave him a treat. This went on for about 15 minutes. In. out. treat. I then worked with the bit by putting my thumb in the side of his mouth and opening for the bit. We worked on this for about 45 minutes until I finally got it in and he was relaxed. He was perfect once it was in his mouth!!!!!
I think maybe someone boinked his front teeth and it hurt him. He was trying to be good and do what I asked him but he was truley afraid, but in the end he did just what I wanted.
I also worked with him in the ring to just relax. Since he is a reining horse he is very touchy and high strung. I walked him and he began to relax and drop his head. when he started doing this I walked him over to the pond and just sat on him while I talked to my friends. He eventually learned to relaxed to where I just put the reins down at the saddle horn and he just stood there with his head down.
He did much better with this new bit!!! Does anyone want a reinmaster wonder bit? I paid 86 bucks for it but will take 1/2 that.
Thanks for all your help guys. You are great!!!
