I was reading raised by narcissists on Reddit and saw someone had posted a like experience, where their NM would run out of the house and leave for hours, supposedly for their "misbehavior".
I hadn't thought about this in years and years, but my mother did this all the time when we were school-aged. She would get angry and pissed off, yelling at my brother or me for something related to housework or some other dispute and tell us she was leaving. She would scream, "I am sick of you kids!" My father usually was not home during these times. She would then go upstairs pack a bag, and get into the car and drive off sometimes for 2 or 3 hours leaving us alone.
We would be crying for hours, and I was scared crapless of my father coming home and finding out we had driven away his wife, and then beating us for it. My brother and sister would be crying and whoever instigated the fight when she left [always me or my brother] would be yelled at by the other two. "Look what you did!"
Talk about forming abandonment issues in your kids. I think of related events how I would not be picked up from school once having to walk 13 miles home from my high school and there is always that nervous pit in my stomach even as an adult waiting for rides from people that I will be forgotten or left. This definitely has to be rooted in childhood.
Secretly even as my brother and sister cried, there was a few times in my mind where I wished she did not come back. I felt guilty over this but it's true. I didn't want her to come back. I imagined her driving to her freedom and maybe becoming a happier person. Maybe she'd smile once in a while. At the age of ten years old, thoughts like, "Why did my mother ever have children?" came up to my mind. There is part of me that never wanted children, my parents complained about it so much.
She would come back silent and sullen and making dinner. No one would say a word and we'd stay far away from her. I would be thinking, "I wish she had run away for good this time." I was one of those kids who wished my parents WOULD divorce, dealing with tag-teaming narcissists was harder then one at a time. I had years of guilt being told I should love people who did not love me.
