Joe says for the past two years, he has felt like a prisoner in his own home, and his wife, Angie, is the warden. He says Angie won’t let him out of her sight because she’s convinced herself that he’s been having an affair right under her nose with a... (more) 21-year-old friend of their daughter. Last year, this young woman had a baby, and Angie says it could be Joe’s. Angie says Joe and the young woman deny the affair and she wants to know if she’s the “crazy” one. Angie wants a DNA test and polygraph exam to prove his innocence. But Dr. Phil says there could be a completely different explanation for all of this, and you won’t believe what it is.
