If your waifu grows older, and you don't like who she has

Was it ever really true love if you can't accept new faults? That's a tough question anon, aging is one of those shitty things 2d relationships often avoid.
I know some people consider some aged versions to be completely different characters (nanoha for example), so there's probably some waifufags that are only married to the younger version and ignore her canon future.

Picture unrelated right?
Chisaki didn't change much and no one loves her anyway.

What would change anyways?

This doesn't even makes sense. When you make a girl your waifu, her state becomes independent to that of the author's and any other anon who waifu'ed the girl. She doesn't change unless you want her to.
