I always hear about how people with BPD experience splitting (loving someone one second and if that person displeases the person with BPD, the person with BPD then hates the person and/or cuts that person out of their life - Black &amp; White).

However, I also hear advice on “how to cut toxic people out of your life” or watch reality shows where someone (who doesn’t identify with having BPD) may suddenly reach a point with a lifelong friend or partner and say “I’m done!” Meaning they are thru with the relationship, angry with the person and cutting ties.

My question is - I feel like many people who are not diagnosed or identified as having BPD experience this splitting mindset but they aren’t considered crazy, psycho or impulsive - yet, if someone with BPD cuts (what they perceive as a “toxic” person out of their life, it’s a symptom of mental illness.

Can anyone help me understand the difference?
