Dear Natalie:
Based on one very short paragraph, assuming your daughter is living at home, with you, I would give you the following advice:
1. If at home your relationship with your husband, another person in the home (or with a person who visits your home, like a parent, a sibling) is abusive, physically or verbally, and she has been and is witnessing such, end that abusive relationship immediately. Then share with her what you did so she can learn from your example.
2. If there is physical or verbal abuse between your daughter and her boyfriend that takes place in your home, do not allow the boyfriend access to your home.
3. Consider sending her to competent psychotherapy.
If you’d like, you can add any details that may help for further communication here.
