Repairing your marriage and repairing yourself are one in the same, thus, you will likely not give up anytime soon on either.
Also, refrain from trying to activly "tell" her or "show" her your changes. Let her come by them on her own. It works better that way. If you are constantly showing her and telling her to "see your changes" then she begins to suspect that you are making them just to get her attention. It's better if you just make them and move forward.
