I have a step-daughter who is a handfull. She has senosory integration disorder but takes full advantage of her mother. She has no manners, is disrespectfull, always wants things her way and does inappropiate things at home and in public. If I say something like stop I'm the bad guy.I'm the bad guy by not putting up with her stuff. If I walk away then they being her family say I'm just running away from my problems. They say that these problems will follow me into another relationship. We have been to a family counselor but I just don't think my wife gets it.
