    You're in a very difficult and delicate situation with someone who sounds deeply troubled. I understand your hesitation to engage with them. Your safety and wellbeing need to be the top priority.

    Rather than trying to change them yourself, I would suggest:
    - Keeping interactions minimal, brief and neutral
    - Setting very firm boundaries on what you will/won't tolerate
    - Encouraging them to seek professional help to work through their issues
    - Focusing your energy on caring for yourself and spending time with healthier connections

    Ultimately, you can't control their actions, only your own. Protect your own peace and safety first and foremost. I'm concerned for you and I'm here to support you through this. Please reach out to others you trust as well. You don't have to navigate this alone.
