I have a similar story. DH has to kids, 13 and 16, who create daily drama and strife. I count daily until they are 18. They both lie and manipulate DH to make me the bad guy daily. Nevermind that they both lie, steal, etc to both me and my daughter. I'm always wrong for being the enforcer for chores, homework, or whatever. I was the one that got blamed for "making her" steal from me. I am the one that gets blamed for her not doing her chores, "if you were nicer to her". I am at the point of crying every night after they all go to bed, and not knowing where else to turn. I have reached the point of photocopying the notes SD leaves for herself to post on myspace. That way, when she gets pregnant at 13, I have backup to show that she was working towards it. Otherwise, I get accused of being the one responsible, and setting her up to get in trouble. I am totally disrespected by SS and SD, and DH allows it to happen. DH blames me for his daughter's behavior; in reality, she learned it from the mother. I am just glad my biodaughter likes my DH and respects him.
