Yes H simultaneously wants every bit of attention on him but also hates any kind of interaction, small talk etc. The 2 things don't go together!
I've noticed lately that whatever he does he does loudly, trying to monopolise the room. E.g. right now he's on his laptop doing some work before we start the day's activities. He's just had a go at the kids for being loud, then on the next breath is shouting and exclaiming about something he's reading. Always one rule for him 
I think I'm noticing more and more annoying things now that we are splitting at last. Latest annoyance: He keeps starting conversations whilst walking away. Why on earth would you do that? So either I have to say 'what?' and maybe have to follow him to keep up. Or else his voice just gets more distant so I don't know what he's actually saying. I know for a fact he'd go mad if I was so rude. The other night he unnecessarily yelled at DS, I tried to talk to him about his shitty attitude to DS and he literally put his shoes on and went out, as I was in the middle of a sentence
if I did that I'd be 'in trouble' and getting ranted at.
Right now he keeps talking at me about work stuff, even though I'm very obviously quiet whilst typing this and previously was quietly reading. Loudly talking AT me. Loudly calling work people. Imposing himself on my quiet time. Yet if I was to talk to him when he's doing something he'd snap at me or tell me to shush, or ask me to go elsewhere to make noisy calls. Again, one rule for him.
