learn to apologize for wrongs you commit, own them (that means you don't keep repeating them) so there's nothing for her to keep hanging onto
if she does-then help her learn to forgive. If you have sincerely apologized for an "injury" to her

FWIW, it's a rare event that my h would want to ML after a big drawn out hurtful fight.
Unless that were the case,
I don't understand women who use withholding sex as a negotiating tactic or form of punishment for something out of the past.
(unless it's in a good fun way).
I say Call her on that.
Stop tolerating it. It's weird.
