that's the opposite of your title. Severing negative communication with an “incompatible” person a big yes yes. you can tell the person that you do not appreciate what she says and you prefer to avoid her form now on.
A puthujjana will never ever become a good puthujjana by living around bad people. Even worse, puthujjanas have zero notion of morality, they do not know who are good people, who are bad people, what are good thoughts, speeches, actions, what bad thoughts, speeches, actions.
Also, living alone for a puthujjana is bad idea too. Puthujjanas must live around the kalyanamittatas, meaning the admirable friends. When there are no buddha, it is hard to find such people. there are plenty of suttas about this
living around the admirable people is the way to have sati sampajanna, or ''mindfulness'' like people say today.
Once you are good at sati sampajanna, you can use sati to transform sati sampajanna into samadhi. THe buddha claims that becoming homeless is for people who are good at setting the citta into samadhi, not for people who are bad at it. Then once you are good at setting the citta into samadhi, you use sati to transform samadhi into vipassana.
this is what it takes to be ready for a monk for the homeless life in a forest
Monks, if he possess four qualities a monk is fit to resort to lonely
spots and solitary lodging in a forest.
Thoughts of renunciation, thoughts not malicious, harmless thoughts,
or if he be not dull-witted, not an imbecile.
These are the four qualities of a monk fit to resort to lonely spots
and solitary lodging in a forest.'
"Upāḷi, it's not easy to endure isolated wilderness & forest lodgings.
It's not easy to maintain seclusion, not easy to enjoy being alone.
The forests, as it were, plunder the mind of a monk who has not gained
concentration. Whoever would say, 'I, without having gained
concentration, will spend time in isolated wilderness & forest
lodgings,' of him it can be expected that he will sink to the bottom
or float away.
Instead the buddha lists various dwellings what to do with them
What is good about living alone in a house, is that you can play the homeless for a few days, feeling safe by knowing that you still have a house if the situation worsens.
