I discovered that my dad cheats on my mom with another guy! I found out after he forgot to log out of his email and it showed numerous conversations with men and private dinners and hotel stays. Almost every month he tells me that he's off to a meeting in Sacramento (We live in San Francisco) but the he has many hotel receipts on his email that are located only 10 miles away from my house. I also read his conversations with another man, his doctor!!! They are supposed to meet tonight at 6 at a restaurant! And so when he got home I asked him where he was going and he said that he was going to a "christmas work celebration," hosted by his boss. I am sooo pissed! My mom doesn't know, and I don't know what to do! I have a little sister and it will tear her heart out if she finds out! I'm going off to college next year and if my mom finds out while I'm away I don't know what will happen. How can this happen to me! I've never been so upset in my life...

Wow, I would have to say that you must tell you're mom, what he is doing is very wrong and if you're mom finds out you knew but didn't say anything she might be a little pissed at you. I'm sure it would be hard, but I think it's gotta be done!

You need to tell your mom what is going on. Nobody deserves to be put through that crap. That is just messed up. I hope everything works out for the best.
