About a year or two ago, my mom caught my dad cheating with some chick in China through photos/phone records/Western Union cash disbursements. She reacted basically by being spiteful. Psychologically, I think it was very unhealthy. She's already skinny and lost more weight. She was tripping balls and had me look at phone records and other pointless stuff for her. I suggested a divorce to start fresh. She refused so my dad could not marry the girl from China, and probably for financial reasons as well. They've been married a long time. Eventually she forgave him. I just received a phone bill for my dad for 4 other wireless numbers. He's in China because grandma is ill, so I thought it be ok to look at his mail for him. I am assuming the other numbers are for making calls to that chick in China. He already has a cell phone and there would be no other reason for him to get 4 other ones. It'll take around a week for AT&T to send the reset password so I can actually see who he called. Should I tell my mom about this or keep quiet? I am leaning towards keeping quiet. Even if she knows, she won't make any constructive changes and just be pissed off about things out of her control again.
