Same here. My mother is a narcissist who lives in denial and makes the rest of her family miserable through her emotional abuse. As a young adult, possibly due to not being able to recognize any red flags, I ended up engaged to a woman who also was a narcissist and abuser, and eventually things led to her holding a chef's knife to my face telling me she was going to kill me and then herself because she thought I didn't spend enough time with her.
I much prefer loneliness to enduring that kind of stuff. I'm grateful to the loneliness, in a sense. I have no master to answer to but my own generosity and patience, and I'd gladly trade anything to never be in a situation like that again.
