Are you talking massive ass here, or just a little bit big?
Asses only get bigger as we get older - especially womens - it's all programmed in with the hips expanding to facilitate childbirth.
And if you have a fat ass, it is pretty much impossible to change it.
So you can either chuck her, and spend the rest of your life looking for physical perfection that will never last, and you will always be disappointed.
But better is to just focus on her inner beauty, and give up your addiction to stuff that will never make you happy.
