You're welcome. I'm going through something similar with someone who is thankfully now in my past, so I understand how tough it can be and how wrong it can feel to think that your actions might be hurting them. But it's important to remember that some people are unreasonable, and it's their own actions and demands that are hurting them, not you - you're looking out for yourself, and that is what you should prioritize. It gets easier the more you do it.

Wishing you the best on all of this. <3

If they perceive you standing up for yourself as an "attack" on them, that is a problem internal to them and you are not responsible for it in any way.

Let toxic people be toxic and suffer the consequences of their actions. You cannot save them if they do not want to change, and you should not waste your time, your energy or your life trying to.

This. Literally just walk away. Stop talking to them, stop interacting with them, remove them on any social media. Do not engage if you see them in public.

I had to do this with a toxic ex recently, and it's literally as simple as telling yourself "I'm not doing this anymore" and being done with them.
