I dont understand how you just drop someone out of ur life that spent 15 years with you with no reason what-so ever. Dottie wanted nothing more than for Joshua to remain still in her life even though he hurt her so bad. She had so many questions that went unanswered and left with an empty feeling. She realized that you don't really have anyone in this world but urself and God. She was faced with the ultimate betrayal. I guess everyone plays the fool at least once in their life. Dottie sure felt like she had.
