They spit everyone, even family.
Something I’ve observed from people with strong bpd traits is that they are always the victim. They always seem to be on the outs with everyone around them, even a majority of their own family. Even if they are not someone with bpd, I think it is a major red flag when a person is always negative and always has an issue with 80% of the people in their life. If they are always complaining and talking about blocking someone on social media or “cutting people off”, i know it’s just a matter of time before I am next.
