I can imagine how angry this must make you, because you are hurting for your mother. My father is in his late 60's and still sleeps around on my mother, with girls even in their 20's mind you. So I hear ya.

I agree that the person you need to confront is your father. I would tell him in no uncertain terms that he needs to figure out how to tell your mother, or you'll tell her yourself. Yes a man (or woman for that matter) needs to know that when they cheat on their children's mother it hurts not just their mother, but their children as well. Just tell him how you feel about it. Who knows maybe your mom already knows? Maybe sometimes women (especially women of a certain age) may have an agreement, even an unspoken one, where they might know something is going on but they don't wanna know. But I wouldn't be an accomplice in denying your mother the truth. What would you want from your daughter, if you had one and she became aware of such a thing?
