Does any expert on the forum know if there is a name for a condition that causes a person to constantly dump people from their life, on the slightest pretext? People who can't keep friends, who refuse to speak to relatives who disagree with them on even minor things? To the extent that this person is left pretty much on their own, certainly by the end of their life. To be specific ...this would be a person whose FIRST reaction to any sort of conflict or disagreement is to decide to permanently blank the 'offender.' And this snowballs until they have virtually no friends or contacts left?
