Hello,
I live with someone, let's call them X acts in a very cruel way towards others (many of whom are very important to me). It is not physical, but works in almost every other way. I don't want to give any examples but I would just say that this behaviour is absolutely unacceptable, and X manages to hide it from others in their life, and the events are unpredictable. I feel very upset and angry when I see X behave in this way, because the others have done absolutely nothing wrong. It is casual cruelty and I have tried many times to talk things out with X to no avail. I'm not in a circumstance where I can avoid interaction with X. Their behaviour makes me retaliate in a way that is unpredictable and I get annoyed with people who might have done nothing wrong at all. X doesn't always behave like this, but when it happens it ruins my day. Advice?
