but why does he keep lying when the truth would suit better.
Same reason my 14 year old son does, BECAUSE HE'S A TEENAGER!
You will see the different aged children within them throughout this. My XW lies about everything. Even stuff she doesn't need to lie about.
I got to see like a 6 year old version of XW this past weekend. We were leaving Church and I was walking to my car with my fiance and 3 kids, my XW came out to the parking lot and was skipping and yelling that she was getting a dinosaur for Christmas. My kids just looked at me like "What was that?!"
Just when you think it can't get any crazier, it will.
