I look at Mumsnet quite often, and to be honest I've never seen anyone told to "go no contact" for no good reason. I often read of horrible situations where parents or in-laws are really dreadful people, making the OP's life a misery. In many circumstances, "no contact" is the only way forward.
In my own younger life , I put up with a mother who was really horrible to me - I'd never heard of the idea of "going no contact" then but I wish I had. Our generation was brought up to tolerate our older relatives out of respect, but sometimes the respect only went one way. Many young people put up with horrible treatment , which only ended with the death of the older person. "Going no contact" would have saved a lot of heartache I'm sure.
