In season three, episode nine of WeTV's "Marriage Boot Camp: Reality Stars," each couple learned how to forgive those who have done them a "grave injustice" in order to move forward in their current relationships.

Camp counselors Jim and Elizabeth Carroll explained that each person in the house needed to identify their obstacles and the people who have limited them in any way in their past. Only then could they fix the current problems that they face with their partners. After the couples identified those who has caused them pain, they were instructed to write a letter addressing that person.

Reggie Youngblood and girlfriend Tami Roman opened up about their own heartbreaks and hardships. Youngblood cried as he spoke about his mother's death during his sophomore year in college. His college football coach didn't extend the utmost sympathy towards him and his situation, so he chose to address that coach in his letter. Roman opened up about being homeless as a teenager after her mother lost her job and also revealed that she was sexually abused as a child by an older man. She addressed her letter to her abuser.

Travis Garland told the counselor about the music producer who managed his boy band NLT. He said that the manager took advantage of him and stole money that was rightfully Garland's and because of that, Garland was left with little money and had put his parents into debt while he attempted to chase his dreams. Girlfriend Aubrey O'Day revealed a moment when her mother destroyed her pageant crowns and trophies when she was a child and she told counselors "I just remember thinking, 'she's my enemy.'"

Jordan Lloyd opened up about being bullied in high school by older girls who would throw food at her and call her fat. Jeff Schroder said that growing up as the youngest child, he faced torment and abuse from his older brothers and never let go of the need to strive to be better than them.

Mike "The Situation" Sorrentino finally let his guard down and expressed the hurt he felt when his own father sold book rights for a tell-all that claimed he was a drug dealer. He cited that incident as the reason why it's hard for him to trust anyone, especially his girlfriend Lauren Pesce. Pesce freed herself of her demons when she forgave the group of friends that she felt had a hand in her little brother's drug overdose that eventually led to his death.

Kendra Wilkinson had to face her mother, with whom she's had a tumultuous relationship with since she was young. She opened up about a time when she ran away from home when she was 13 years old and her mother never went to look for her. She said it drove her to do outrageous things like pull chunks of hair out of her scalp. She told counselors "that's the only time I get attention is when I do something like that."

But her husband, Hank Baskett, was the most closed-off out of the group. He chose to focus his forgiveness letter on his childhood asthma, and Jim forced him to come face-to-face with the person he felt hurt Baskett the most, the transgender model who claimed Baskett cheated on wife Wilkinson while she was eight months pregnant with their second child.

"I forgive," Baskett said, finally breaking down. "I forgive you for this pain you put my family through my, I forgive you for what you've done. I forgive myself. I forgive myself for this pain that I put on myself and the people I love. I forgive."
