I was married 8 months ago to a widow with three children, 2 daughters (11 & 17) and a son (13). I have a duaghter who is 13. The 4 kids live with us. The problem is the relationship between my step-son and my daughter. I thought it was a matter of my daughter getting used to a brother who teases her, because that is what he does in front of us. However, my daughter has been extremely upset and has started telling me about what happens when the aults are not around. She started a new school this year (we moved about 1 hour from our old home), which his kids already attended.
