She has said she's forgiven me but keeps reminding me of what I've done.

It doesn't sound to me like she's really forgiven you then if she keeps reminding you of what you've done.

I have been working the 180s regardless and trying to be the man I should be. I think it's too late to save my M; hope it's not too late to save me.

I think this is all you can do.
