Dear Pema nails it on the head again.
If there are whole parts of yourself that you are always running from, that you even feel justified in running from, then you’re going to run from anything that brings you into contact with your feelings of insecurity. And have you noticed how often these parts of ourselves get touched? The closer you get to a situation or a person, the more these feelings arise. Often when you’re in a relationship it starts off great, but when it gets intimate and begins to bring out your neurosis, you just want to get out of there. So I’m here to tell you that the path to peace is right there, when you want to get away. — Pema Chödrön, From Practicing Peace in Times of War
