Apparently, 20-year-old Avery took things into her own hands by writing her father a scathing letter, while accusing him of breaking up their family.

According to OK! Magazine on Friday, Ramona published parts of the letter in her book, which said, "I'm writing to you again because I hope that, as your 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."

She continued to slam her father by writing, "We were a trifecta and you broke us. 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. This whole thing is an embarrassment to Mommy and me, and you have not once thought about how it would affect us. I am ashamed of you."
