I had the same problem, found out I was right eye dominant, look up the test, it's easy and you will know as soon as you take the test, I now cue with my right eye over the cue shaft as opposed to my nose, I wish words could explain what a difference it has made in my shot making ability, the cruelest thing is that my aim looks the same to me whether I line up with my nose or my right eye over the shaft but I get right english when sighting with my nose over the shaft and I shoot center ball when my right eye is over the shaft, try it for yourself, one of guys on my pool team is left eye dominant even though he is right handed, he has to shoot with his cue stick just left of his nose, stance, stroke ect. could still be a problem but if your eye is telling your brain center is to the right it will be harder to fix those other things, hope this helps you in your pool journey, wished I learned this sooner.
