Is AUTHOR wrong in the post ? POST : Hi all,

So this has been eating away at my conscience for years and this happened about 10 years ago when I was 8. My mom was living with my stepdad  and we lived in Arizona. A year before that, my stepdad sent us away to my grandma's house for no reason at all, but my mom saw some dating sites in his cousin's computer history, so she accused him of "cheating" on her with girls on the internet. Well, the next year my mom and I went on a little "trip" to Mississippi because that's where we were originally from. Well, my mom completely lied to my stepdad about what happened when we got there. About a month prior to us going to MS my mom met this guy on Myspace named "Mike" but my mom wanted to keep him a secret so made me refer to Mike as "him". When we got to MS she sold her engagement ring to a pawn shop and then we went to Mike's place and I honestly thought he was gonna be my new dad. Mike and my mom would spend most of the day in the bedroom doing god knows what in there while I would be in the living room playing Tony Hawk's American wasteland all day. Well, it didn't work out the way mom thought and we ended up going back to my stepdad. She completely lied to him and even said she "lost" the ring and was with her friend over there and he actually believes it still. Now, I would let this stay buried, but almost ANY time they get into some sort of argument (usually my mom screaming at my stepdad while he tries his best to ignore her) she ALWAYS mentions how he "cheated" on her because of the online stuff and she still has NEVER told him the truth. It really boils my blood and I don't know what to do
