I think it's great that you do see your faults and what you would like to change.
If this is something that you truly feel you need to do for you and nothing more then I would go ahead and do it. Apologizing numerous times however isn't the way to go, but if you haven't apologized at all yet, then again I'd say why not if it will bring you peace.
You need to be careful though, his reaction may not be a good one and this could very easily lead to a R talk if you let it. You have to practice some serious self control and be aware of the mlc mind you are dealing with.
Remember where he is at right now, your apology most likely won't have an effect on him. But it sounds like you're aware of this and your doing this only for you. No expectations.
