An older version of me cut people off without a conversation. I realize now that it was wrong, and that I was scared to have the difficult conversation. So I ran away instead with the excuse that they were bad people and I needed to leave the relationship. I wonder if some of that was in play for you? Conflict resolution can be quite nuanced, and it takes a lot of courage to face these situations head on to try to come to a resolution, or to at least advise the person that you are upset and thinking about ending the friendship.
