Of course you care and you will continue to care. But you need to take a look at yourself. Do you want THAT marriage back? The marriage that has left her feeling unfulfilled and you feeling that it is all you have?

The answer really should be no - like you said, you want to start over. Start as if you have both died and are going to get a fresh chance.

You cannot change your wife and therefore you need to look inside yourself. You've already said that you deserve better. That's a good start:

Why do you deserve better and what would "better" be?
What do YOU want out of a relationship?
What do you want out of YOUR life?
etc.

Now, what do YOU need to do to obtain these goals?
