Relationships and Sociology

I was looking on another board that was talking about INFJ doorslam. Someone described as a "tactic" used by INFJ, like it was a form of manipulation or control. At the very least this person thought it was a controllable decision.

Personally I feel like it's a deep part of my brain that door slams. If I do it, it's after I have given the person EVERY opportunity to redeem themselves, but they screwed me yet again. Granted, it's sudden. A switch flips and it's over. There have been times...
