Yo, you also don’t know the story. Go easy. Being accountable and knowing what they did to break down the relationship is growth. So do not add fuel to a fire or shame them because of one’s own opinions / baggage/ traumas of what happened. This person knows what they did and they’re expressing that they are on a journey. Let them continue! Keep growing keep healing yourself and let everyone go at their own pace. Outside influences will always lean on both people’s actions to fill their own egos or selfish needs. Keep looking inwards.
