Hello and Thank You for using Just Answer. There are a few options:1. You and your husband and step daughter need to all sit down and have an open and honest communication session. Allow everyone to speak and try to come up with reasonable solutions to problems without becoming angry. 2. All of the same members involved should attempt to seek family counseling/therapy together. 3. Press charges against your step daughter if she assaults you but this may cause even more friction. 4. Separate from your husband for a while. 5. Request that the daughter move out. She is using her dad to her advantage and he is enabling her to continue to act as disrespectful as ever. I hope that I have provided some insight. Your will have to decide what to do and what you can truly live with in order to be happy and have positive relationships. Right now, you are dealing with a husband and step daughter that you do not trust, a husband who suppots his daughter over you, and a step daughter who has many emotional and physically aggressive issues.
Have a good day and hang in there.
