Well, I told my mom that I knew, and she treid to convince me that he already knew but I didn't believe her so I made her tell him. My dad was really upset, but he thought about it and told me they've been married for 24 years, and that they made vows to work things out when they got married, and that he has some responsibility if she is cheating on him, so they went to counseling for a couple of weeks but now she's moved out and they've sepparated, sooo... they're still amicable, but things are prettymuch over. I can tell you, it was great advice I got here and the weight and responsibility that was lifted off me was sooo liberating once I told them. It turned it from my problem to theirs and that was so much better! Thank you everyone! :D:D
