Polaris, I feel in a similar situation to you. My DH is not as severe as yours but he does have a temper and likes to get his own way. However I think he is spoilt, rather than abusive or controlling. His temper isn't frightening, more like a toddler's
.
We have been together for 15 years.
What I have learnt on here, and through counselling (not for marriage problems but something else) is that actually my father was exactly like this (well I knew that anyway) but that it was not a normal way to behave. It was not OK to shout at your children and your wife and then (when they did nothing and it all blew over) pretend it never happened.
I loved my father dearly and would never ever say that he was abusive but, to a dispassionate 3rd party, he may well have been, and was certainly controlling. He died before I really left home, and I never put a foot wrong at home, so I never got to find out how he would have behaved if I disobeyed him or did something he didn't like.
But back to my DH. I love my husband very much and have chosen to have two children with him. I still want our marriage to work.
However, I realise now that I do not have to be treated the way he often treats me, that I do not have to put up with behaviour that he would not find acceptable in me. So I have changed the way I deal with him.
I will not allow him to shout at me or be dismissive, I will not react to his tantrums (usually around lost keys) or enable his behaviour in anyway. I refuse to be cajoled into certain things either by his stropping or sulking.
I also now confront his passive aggressive (and very subtle behaviour) head on and call it what it is.
It may sound like more trouble than it's worth but I do believe things are getting better, or at least I feel better about it.
If at some point DH decides that he doesn't like my new found assertiveness, then that's his choice. He can either moderate his behaviour or leave.
What I'm trying to say is that you have a right to live a life that you are happy with. Apart from the normal social conventions, you shouldn't have to justify your actions, tiptoe around someone or factor in their reactions to something. You have a right not to be with that person.
Noone is perfect, it's true, and only you can decide whether you think this is behaviour that could change if you changed, or not.
If you are frightened of standing up to him because you are afraid of what might happen, then you really do need to get out.
