BPD splitting feels like an intense emotional rollercoaster, rapidly shifting between seeing someone (or yourself) as all good (idealization) or all bad (devaluation), with no middle ground, often triggered by perceived rejection or small flaws, leading to extreme love/hate, sudden rage, impulsive actions, and chaotic relationships where a supportive partner becomes a villain in minutes. It's a confusing experience of black-and-white thinking, causing deep instability and distress, making it hard to see people as complex individuals.

This protects them from pain by simplifying a confusing world, but it leads to rapid shifts between idealizing someone as perfect and devaluing them as terrible, often after minor perceived slights or triggers.
