Means he will continue to use whatever "it" is to harass and demean you. If he had truly forgiven, he wouldn't bring it up and throw it in your face. You can draw a line in the sand and tell him you are tired of it and then dump if he continues, or you can learn to just put up with it,
If he's forgiven you for whatever you did then it's over, he has to let it go and not keep rehashing it. If he doesn't then let him go.
