"I'm writing to you because I hope that, as you daughter, I will be able to get through to you. You need to stop and fix your actions before you lose everything that is good in your life," Avery penned in the emotional letter. "We were a trifecta and you broke us."

According to The Inquistr, Avery feels deeply ashamed by her father and his actions, and she had no qualms about letting him know it.

"This whole thing is an embarrassment to Mommy and me, and you have not once though about how it would affect us. I am ashamed of you," she honestly explained. "What you have done and are still continuing to do is now forever damaging. You have no one to blame but yourself. It's about time you stop acting like a teenage boy and take responsibility for your actions."

She continues to attack her father's actions in the letter, wondering how he could sleep with Dexter in the house that she grew up in.
