Doormatt I have same issues with my SD6. Who acts more like she is 16. I also have the added stress of her mother who does not want to let go of my boyfriend. The child is very unstable and causes much grief in our home. Over the past couple of days I came clean and told my boyfriend how I feel about his daughter. It was hard because no matter what it is his daughter. I was surprized to hear how much his eyes and ears are really open. He agreed to alot of her behavoir I brought up and said its wrong and that he is disturbed by it also. We both came to an agreement on some new boundries in our house for her. So dont keep it inside and let it eat at you.It will consume you until there is nothing left of you. Share it with him even share your fears of how you feel he may react. Its better to be honest and communicate about it. Its the only way change will happen.Good luck.

I agree, I've kept some of the more nasty things inside, but I've told FH pretty much everything that has bothered me about SD over the years, and yes, there were times when he would take her side (especially when she was young, he'd say "she's only a kid, you're the adult, etc.") but as she got older and the same things I mentioned when she was little just stayed the same or got worse, he started listening. Her mom has seen these things from the beginning too but refused to admit it at first. Now she has put in the call and we're waiting for SD to get an appointment with a child psychologist (or so BM says. It's been a few months and we haven't heard anything). But I told my FH that he needs to keep an open mind because he doesn't understand my side of things, so I can either tell him how I feel and he can try to understand, or I can keep it inside and resent SD more and more because no one will listen to me. He chose to keep an open mind, and though sometimes he hears things he doesn't want to hear, he knows it's better for us in the long run if I can vent to him (instead of unleashing on her).
