Their daughter, Alyssa, was 12 years old when she says her mom shared details about her dad's affair. "I knew my life was going to change at that point," says Alyssa, 19, who says she has moved 19 times in the last seven years. "I felt like I had chaos and instability in my life from moving so many times, and I had to drop out of school. I was a very angry teenager."

Watch the video above as Alyssa describes what she witnessed as a child, why she says she's concerned about her 12-year-old sister, and her stern advice for her parents who she says need to "wake up and take care of the kids they still have."
