Today I went on my dad's laptop and his email was up, and I accidentally saw some creepy email from a girl i've never heard of before. i know it was wrong but i had to keep reading it. i saw all his emails and a lot of them were with this girl, and they were really creepy talking about innapropriate things that i dont want to repeat...
they also talked like they had met up before, or were at least thinking of meeting up. she keeps saying how she's moving to my town in the emails. my dad is still married to my mom and they have a really good relationship- it seems.
a couple months ago i was on my dads computer and found this dating site which he talked to other girls on so i confronted him about it. he acted like there was nothing to be worried about and it was a joke with him and his friends. i let that go even though i didnt believe him.
now i dont know what to do- should i confront him? should i tell my mom? i cant just sit here and not say anything, i feel like that would be wrong. but i also dont want to be the reason that my parents split up. i feel so bad for my mom i almost dont want her to know because i dont want her to be sad or embarrassed. but i also dont want to jump to conclusions, maybe he hasnt actually ever physically cheated.
what should i do!? help!

Ask your mom if her and ur dad are distanced or whatever... Judge her reaction, and then go confront your dad about it. Make sure to use the woman's name :]

Obviously he's not gonna be happy that you know, but in your defense, you have the right to know, since whatever happens will directly affect you.

Well your mom is going to find out anyway so you might as well tell her. It won't be your fault they split it'll be your dad's

Go up to your father and tell him what you know. Make it known that you can and just might use this against him, in the sense that you can easily let your mother know.

You've got him by the balls. If he's not cooperating or tries to squirm/lie his way out of it, I think it's best to let your mother know.
