Of course, what you could do, is have your balls surgically removed, preserved in formaldehyde, and mounted on a nice plaque. Then present them to her along with all your apron-wearing, housecleaning, grovelling behavior.
I think a sincere apology and remaining quiet is the best plan. And modify your future behavior, of course.
If she is able to accept your apology and, within a few days, move on, then she's a pretty good woman.. If she continues to make you pay with grovelling, then you might want to think about whether or not its worth it.
Some posters here seem to think its ok to be a sucky, supplicant. Certainly apologize, but no grovelling!
I think she will, in the end, respect you more if you act like a man, not a suck.
In my opinion, mutual respect is the most important element in any relationship.
