It sucks when you choose to stop contact with someone you thought fit just fine in your life. It's also not helpful when they live under the same roof.
A few hours before I typed this post, my brother and I got into the most useless conversation about certain viewpoints. Actually, it was less of a conversation and more just him being increasingly loud as though I wasn't sitting right in front of him. Almost every time I started to speak, he came at me with his incendiary verbiage attacking my living situation, my relationships, and my religion (or lack of religion. Being an atheist didn't fit into his world view apparently.) I tried not to raise my voice, but his constant interrupting was upsetting me. I don't mind real talk about stuff, but when he clearly doesn't want to hear what I would like to contribute to the conversation, then that conversation is over.
Once I got a clear thought break through his mouth noise, I was transported back to heated arguments with my ex. If things didn't go his way on his time, then there were problems. A narcissist doesn't realize that he's not always right. When I connected my brother's tempestuous dialogue to my ex's unbridled behaviour, I no longer felt like I was talking to a brother. People like that are not people I want to know.
I did say, outloud, with words, that I was done with the conversation. He refused to respect that, so I left him still talking at El Cometa... and he walked home.
I'm sure me ditching him will be the only part he'll remember to tell in the story about how his family doesn't understand him. Oh well.
