Bio mom is a liar. No nice way to put it. Most likely an undiagnosed personality disorder is to blame. Idk. She's taught the kids to lie. It's disgusting. DH is the most honest person I have ever met. We tell the kids always "be honest, be true & all good things will come to you" The history of lying is long & tiring. Just when we thought there was no hope... The kids have begun saying "Well we are suppose to tell you -----(a lie) but it's really ----- (the truth)" Finally a glimmer of hope.
