I handle it basically as you did (are doing): If the complainer won't accept any accountability for his/her predicament, there's nothing that can be done. Until they can stop the blame game there's no point in conversing about it.
BTW: ENFJ's seem to have this as a theme. I went out with one for a while, explaining to her at the outset that I was seeing other women and would not commit. We had fun going to bars and being each other's booty call for a while, developing no intimacy and showing each other behavior that doesn't in any way lend itself to a long-term romance. When she started to try to manipulate me into a real relationship, I gracefully backed away. At that point I became the horrible villain: "Look what YOU DID TO ME!!!". It's a feeler thing, I suppose.
