Should I tell my mom that my dad is cheating?

I think you shouldn't.

yes.you better should tell her before it is too late.initially it will be hard for your mom to believe it but you should do your bit.if she comes to hear from someone else then she won't believe it and it would be too late.then there might come a situation where she won't even believe you.so hurry up and tell her the truth.don't worry.

Are you sure that she doesn't know? Sometimes people don't mind "looking the other way" when someone they love is doing something they shouldn't be. Maybe losing your dad over him cheating isn't worth it to her so she chooses to act like she doesn't know. Is your dad cheating with the same person this whole time or is he "playing the field" and it's someone new every other week or so? Sometimes that can make a difference. If he has a lot of different women, chances are your mom knows and chooses to let it go. What do you hope will come of this? If she honestly doesn't know, how will it effect her that "everyone knows" and chose to wait 10 years or so to say anything? Do you feel guilty about it (knowing this long and not saying anything about it) and that's why you think she should know now? Do you think things will really change? She'll leave him or he'll stop cheating? Will she be able to handle starting over if her marriage tanks? Can she emotionally handle this news? I'd want to tell my mom but I honestly don't know if I could if it had been going on for that long and I never said anything before. Another thing, would she believe me if I did tell her? Would she "hate" me for telling her? Hurting her? Would my dad play it off like I was a liar? Would it sever the family ties because they pulled together and decided I was trying to make trouble for them? Would I have proof if need be? This is a no win situation, to be sure. :( Good luck in whatever you decide.

I bet your mom has some strong suspicions. Maybe she stays with him just for your sake. I know that if my man were cheating and my daughter knew, I'd want her to talk to me. Still, he is your dad and it might strain your relationship with him. I think maybe it would be best to talk to your dad first and give him the chance to tell your mom.

After reading this i think you should inform your mom about your dad that he is cheating because after so much years also if your dad cannot be dedicated to your mom than what can anyone say.This situation was same with me and yes i said everything to my mom they fight but again he said sorry and admitted his mistake now i think he is not doing this.Hope so...

My dad has been cheating my mother for more than ten years and many people were even telling us but we never agreed because we said we know our dad more than anyone else, after all these years it came out to be true when we started suspecting him of giving that woman money so we had to tell mom and she is such a strong lady that she took everything strongly and did her research, we all finally came to know her and we have not said it to our dad but we give him hints now and then and after some times he realized and left that woman, my mother is still hurt but its better to tell her that hide from her.

I think you better talk to your dad and kind of blackmail him that if he does not leave cheating on your mom you would tell everything to your mom. First try to make him understand in a polite way. Otherwise just tell your mom if he does not listen to you.

You knew all this time and you haven't told her? I think you should tell her. I know you shouldn't meddle in someone else's relationship but that's family you're talking about. If you know that a member is doing something wrong, even if it's you're dad, you should let the other family members know.

First off how did you find out he was cheating?? As others say, the liklihood is your mother already knows, 10 years is a long time, but they may even have an arrangement, he sticks with her for families sake...it may be for reasons you know nothing about...but I do think you should broach the subject with her.

I'm not sure that YOU should tell her. But SOMEONE SHOULD tell her. And the BEST one to tell her is your father himself. The most important thing is honesty.

definitely yes!

Oh, that's such a hard thing for you to have to deal with! I think you should really talk to your Dad and ask him to choose betwen your mom and his other woman. HE should sort this out, not leave you in such an awkward situation. I had a similar thing when I was in my 20s, my Mum started having an affair. It was her choice, but I didn't like it and wanted to hear nothing about it. In the end, my parents split up and both are happier now with their new partners than they were together. Good luck!
