A 23-year-old stepdaughter, who moved in with her parents four years ago, has been absent for several days and often leaves for extended periods and doesn't inform them where she is. Her stepdaughter's room was a mess when she returned home from a visit and left a nasty note accusing her parents of violating their privacy. Her father and me both expressed concern over her absence and told her lifestyle is not welcome in our home. They need to clear their expectations about how shared space works and what the ground rules are for their shared space should be established. Suggesting that talking to your daughter about these concerns could help keep her informed and informed about future activities and activities. However, there are concerns that the boyfriend's behavior could lead to mistreatment of her daughter and potentially disrupt her relationship with him.
