Or at least can anyone help me find a simple way to understand/explain it please? Say for instance I asked DH to go out with his mates a little less, maybe twice a week instead of three times and his response was to get angry and say 'ok then I won't go out at all', what would that be, other than childish? That scenario is completely hypothetical btw but the circumstances it actually does happen in are either too subtle to be good examples or too outing.
The overall feeling it leaves me with though is that I'm being punished for daring to disagree with or challenge him, like I'll ask for a small concession and he insists on going the whole hog to make me seem unreasonable. In the example I've used I would then spend ages arguing that I never asked him not to go out at all, just a little bit less and he would keep insisting his extreme solution (not going out at all, ever) is 'obviously' what I want and 'it's just easier', implying I will make his life hell if he does anything else even though that's not what I asked for in the first place!
It's maddening as you can imagine but doesn't happen often, just when I threaten to interfere with something he wants to do which is doubly annoying as I only ever object if there's a clash with family responsibilities, I want him to be happy so definitely not out to spoil his fun! It can happen over non-fun stuff just as easily, I asked him once not to book any work for a particular Saturday (he only works Saturdays occasionally anyway) and he threatened to close down his business and 'go and find a dead end job' 
It just feels like he does it to make me suffer for daring to question/disagree with him although he swears blind he's just 'trying to make me happy' when I call his behaviour out. It's scrambling my head that I can't put what he's doing into words, it's so hard to push back against when you can't name the behaviour, does that make sense to anyone? It's not about explaining it to him even, I know he knows exactly what he's doing, it's just hard to call him out when I struggle to describe what it is he's doing. Can anyone else describe it better than me please?
