To help you, when the instructor is there get a third party to video with the sound on. Then view it at home.
But the key thing about feel is that you feel at one with the horse
I agree with Barry about this. Some people never really find the sensitivity to feel all the changes your horse is making. This is not to say that you will never be a great rider.
The amount of time you spend in the saddle with your instructor telling you when it happened as Wallaby suggested, is very helpful but if you are only riding once a week for an hour, you may never feel it - you need a lot of time and concentration to learn it.
Frankly, I've owned horses for close to 30 years and I ride several times per week. I can feel when a horse is wrong or off, I can even tell you which leg is causing the problem. I can usually tell which diagonal I'm on. I am normally in rhythm at all gaits and can sit most antics a horse puts on but I could not tell you the very finite things a horse is doing at all times and never could.
