Yes, Bobby, cheaters do lie. Nearly 100% of the time. That's reality, and you're going to have to deal with it, and come up with a plan on how to protect yourself and your son. Wailing about how "unfair" it all is, and wallowing in anger is not going to help you. Give yourself a day to do that (and some moments from time to time -- it's natural), but then get to work, asking folks here for help.
