You're absolutely right! The advice I gave above does not cover situations where physical violence or serious cycles of abuse are involved. That is a spectrum of problems I have no experience or business speaking on so I stuck to the things I do know.

As somebody recently coming to terms with a history of not treating people great, it is 100% best for you to create distance. If you've been hurt deeply for a while, then you need to take care of yourself first in this moment.

But one thing I will say different from some others in this thread is this: don't just ghost them. You don't necessarily owe them the courtesy of explaining to them why their shit stinks, especially if this has been happening consistently for years, but it is important for yourself to practice openly communicating how you're really feeling here. You certainly don't need to try to fix things. Make it clear to them and yourself why you need to create space. You don't owe them a letter, or even a conversation. But a simple message succicntly and firmly explaining your reason for backing off (being treated poorly) can go a long way. That way, in the future if you run into similar problems with new friends, you'll be able to articulate your needs in the relationship sooner and address the problems from the root.

The longer we let things fester without really talking them through to an end, whether that be reconciliation, relegation of your relationship to just being acquaintances, or the termination of a friendship, the more complicated and deep rooted some negative feelings like resentment and betrayal can really become. It can be hard to dig yourself out of that hole
