My bfs 6 yr old daughter has been very mean lately. Weve been dating a year. Shes been mean, sarcastic, insulting, whispering when hes not around that she will never listen to me. She totally respects her mothers girlfriend. Had a big fight yesterday when I said that the daughters rudeness was driving me crazy. Bf said that he would kick me out so fast. I realize he felt backed into a corner and that i was attacking them, but he was with his daughters mother while she had her son and he to this day feels animosity for him. So he shoild get it.
