Advice for letting go of resentment

Good morning ladies, I need some advice. My husband and I are going to counseling and through it i realized that I am holding on to resentment from previous fights with my husband. I want to be able to move forward with our marriage but I can't seem to get past somethings that have happened. Because of this I feel like I'm stuck in a never ending cycle of hurt and anger. What advice would yall have to help let go of the past and forgive and move forward? I know I'm not giving a lot of specifics but I don't want to talk bad about my husband.
