Yes, ESTJs are some of the worst about bottling up their emotions and then letting them explode...worse than most for sure. Interestingly, I have seen INFPs exhibit similar behavior for completely different reasons. (For them it usually has to do with being so conflict-avoidant that they never stand up for themselves, but ironically this can lead to the same relationship problems that ESTJs create for themselves through the exact opposite behavior!)
ENTJ and INTP tend to be the most emotion-stupid types, in my experience (though ENTP, INTJ and ISTP tend not to be too great at it either.) ESTJs aren't quite as bad in that regard because being SJs, their moral codes tend to be more traditional, and most traditional moral codes involve the idea that you should have some respect for the feelings of others...I suspect that by and large, ESTJs feel more guilty about being "mean" to people than do their ENTJ cousins.
NTs are much more inclined to simply intuit their own moral codes, and so you get a disproportionate amount of ENTJs who see emotion as weakness and flat out don't give a shit who they step on emotionally. As for INTPs, well...they haven't yet figured out a reason that emotion should exist at all; most of the ones I know are really intent on not showing emotion at all. I suppose it's a Thinking-dominant thing?
