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?
How do we both start over when I am the only one that wants to stay married. Grantit we both have changed. I really do want a fresh start but I have to make that happen. I know that I can not change her, I just want to show her that things can be different. I deserve better because I am a generious, caring, thoughtful, faithful loving husband, yes I have made mistake, we all do. I would anything for another chance with my wife and to start a new marriage. What do I want out of a relationship? I want my relationship to be honest, open. To be able to talk and discuss anything. I want to share all of the love I have with someone and want them to do the same. Someone that knows that we can work out problems. I do not want to be lied to anymore. What do I want out of life? I want someone to share my life with me. Someone to start a family with. Someone to share my hopes and dreams.
