Is it time to end a relationship when there is resentment?
It’s time for both people to take a good dose of humility, learn how to forgive, and talk things out. You mostly need to talk about how you will avoid letting resentment build in the future. This talk would not be a chance to try to get your way or point accusatory fingers at your partner. You both need the humility to admit your own faults, and the grace to truly forgive the other.
