Long-standing Resentment Towards a Partner

Long-standing resentment towards a partner is usually manipulation. Even if the person has hurt you very badly and you can't forgive them, think about why you are in this state of resentment. As a rule, this means that you are expecting something from them that will change your opinion of them. But if it is so difficult for you to forgive the situation, you may not be able to forgive it. And if you want to hear something specific from your partner, it's better to ask them directly.
