AITAH for wanting to cut off my mother after years of emotional manipulation but still wanting to talk to my siblings?

This is a community like r/AmITheAsshole, except unlike that subreddit you can post interpersonal conflicts. Anything that's AITA including relationships, hypotheticals, even posting about Scar from the Lion King and trying to convince redditors that he was not the AH. AI scenarios/posts are not welcome or tolerated. An elaboration on our rules can be found here: https://www.reddit.com/r/AITAH/wiki/index
