Everyone needs solitude at times, and healthy relationships include room for both partners to have time apart. The difference between needing space and pushing people away is in the motivation and the pattern. Needing space is a response to a genuine internal state. Pushing people away is a defense against vulnerability that activates regardless of whether space is actually needed. A person who needs space feels refreshed after getting it. A person who pushes people away feels relieved in the moment but lonely in the aftermath, because the distance was never about recharging. It was about avoiding the discomfort of closeness.
Dr. David Steinbok helps adults from the Boynton Beach, Florida area examine this distinction in their own behavior. A therapist who understands why people push others away can help a patient recognize when the urge to withdraw is a healthy boundary and when it is an automatic defense operating outside of conscious control. That recognition is the foundation for being able to respond differently.
