I've had 2 times in my life when I didn't hear from my mother, and YES, they were peaceful indeed.
The summer I was 19 years old, I left to go work up in the mountains at a resort. In doing that, I also moved out of Mom's apartment, and into a boyfriend's apartment. Mom pitched a truly royal fit. When I left anyway, she wrote me a vituperative and ugly letter, which I ignored. A month letter, I got a letter firmly chastising me for rude behavior, which I ignored. Over a month after that, I got a nice letter, which I answered. But all that time, I got and gave no phone calls, and THAT was the peace I needed.
Many years later, after I was married with children, Mom demanded that I, or failing that, a friend of hers, do a lot of driving around (easily 4+ hours...) on Christmas Day to get Mom from friends house to my IL's house, where we would be that day. I refused to do it, told her she was being selfish in the extreme, and that we would rent her a car so she could drive herself and not impose on anybody else that day. She took GRAVE offense at being told she was selfish, and told me she wouldn't see me on Christmas if I was going to behave that way, and hung up! I didn't hear from her for 6 months or more.
There's a lot more to it than that, but that was the start of about 15 years where I saw my mother no more than 2 times a year, if that. It didn't really resolve itself until we discovered she had the beginnings of dementia and could no longer live alone. For decades before that, she was a bitter old lady who caused scenes at family events to get her way, read everybody the riot act when she thought they misbehaved, (which only meant they didn't give in to her and her demands) and churned through friends at a rapid rate as she burned through them. None of the greater family will have anything to do with her. It's a sad way to live.
