I believe "circular arguing" is what this tactic is referred to; the disordered person continues going around and around the exact same subjects
the problem with seeing it this way is that a circular argument requires at least two participants. usually a circular argument is both parties repeatedly stating their position, and/or baiting and switching. in my case there was a lot of "you did this" "yeah but
you did
this". no resolution. often times it helped when one of us (usually me) took a time out. having said that, there were times i escalated when she took a time out, and times that i took a time out only to take the bait and respond.
both sides become entrenched, and emotions run high, and usually both parties feed into the circular argument with a need to be right.
