Not sure if this is any help, but as a child i was a victim of my parents' mostly psychological/verbal against eachother. My father used to get angry when drunk, get loud, spit at my mom, and once or twice gave her a black eye. Also there were times when we went to visit grandparents hundreds of miles away in a car and that would almost always end with them bickering in the car and my father swearing he would stop the car, make my mom go out and leave without her. (I remember, even being small, thinking i would rather be the one left alone on the side of the road)
My parents never protected me from witnessing their behaviour towards eachother. They would scream, fight, knowing the walls were not exactly soundproof. My mom did try to cover up how she got her black eye by saying she fell against a cupboard, but the truth came out one night when dad was drunk again and yelled at my mom, if she didn't shut up, he would give her another black eye.
The results? I have no desire to ever interact with either of them, but that may be due to other reasons as well. I hate any kind of confrontation, loud speaking, yelling. I didn't have any friends at school because my parents weren't exactly giving me an example in how to be nice to others and make friends. I was severely depressed from the age of 10 to about 19, when i finally left home.
On the positive side, now i know what kind of life i do not want. I know i would definitely rather be alone than in a relationship that makes me miserable.
They are still together. Why? I don't know. My father still drinks. My mom still stays. There's still the unbearable tension and awkward silences and unspoken rules in their house. It's awful.
(Sorry for the essay)
