As invincible as you think you are, stuck, this goes over and beyond the line of cocky. It definitely sounds like your mom raised you to be the kind of person you are, which is pretty sad in itself. Do you not realize the damage being done by you and your mother to these children? Or do you just not care? When your kids realize the kind of people you and your family are, they probably won't have anything to do with any of you. Pretty sad that you are ok with your own mother talking crap about your kids' mom to them. If she has half of a brain, your X will be taking this issue to court real soon. And she will get what she asks for. We know, then you will go behind her back and take the kids over there because it is your mommy. And then, when you get supervised visits, make sure to come here and tell us all about how your X is screwing you.
I tried being normal once. Worst five minutes of my life.
