Wow! Thanks for all the replies.
It's interesting to read what you have all said. This is going to sound ridiculous but I tend to agree with all of you. There is a dichotomy where I feel this is very wrong but also where I feel it is only one part of his behaviour and he isnt violent so is it as bad as I feel it is (tbh I think it is).
It is hard to say if the good points outweight the bad. He has many many good points and really (apart form the usual niggles that we all have) only this one bad point. However it is a big bad point. I think that when he has been very angry it feels as though it outweighs the good, but when he has been fine then there is no way I would want to be apart from him. tbh I don't want to be apart from him anyway, just to get him to change this part of his behaviour.
Controlfreaky - I have often thought about the points you made, the effect on our DCs etc which is why I am worried.
Jooly - thanks very much for your insight. DH and I have discussed this before and he has explained how he feels in a very similar way.
Dittany - this is the thing. He is a very big guy and that makes him pretty scary when angry. He is also very strong. My DCs do seem a lot less scared of him than I would expect them to be which made me wonder if I was over-reacting. I was terrified of both my parents (my mum was much worse) and there is no way on this earth I will put my DCs through that - it stays with you throughout life.
Re the pushing bit - he pushed me out of the way, he didn't walk over and push me - I was between him and the door and he needed to get out - I don't even think he saw me at the time. It was witnessed by a lot of colleagues.
Atilla - I think he is embarrassed by his temper hence why he doesn't find it easy to seek help. He is not a big talker and keeps things bottled up (doesn't help at all). To clarify with the anger management course, he didn't quit as such, the therapist did not want to continue the treatment at the time becasue DH had just lost his mother (who he adored) - he was devastated and found it hard to concentrate on the work involved to overcome his anger. That said, I know for a fact he told the therapist he had bought a book recommended to him but he hadn't. Hardly shows committment but then I think he will need a lot of encouragment to work on this and I had no idea he had been told to work through this book.
He screams at the DCs sometimes and swears at them. I tell him to stop, he says
'why?, they do it to me (i.e scream)?'
my response - yes they are 2 and 4 you are nearly 40 .
How do you deal with that sort of pathetic attitude? I've told him it is pathetic, he shrugs his shoulders, I repeat myself, he storms off in a huff. When things calm down I try to broach the subject again - same response.
I have decided that next outburst is going to lead to me suggessting he goes back for more anger management. I've been putting off doing this recently and burying my head in the sand. With the new addition to cope with plus the two DCs being hard work I really don't know how I can handle it all but I have to for my DCs.
I'm also going to get a book I read about on here called 'how to talk so your kids will listen....'. I think it would help a hell of a lot if he had better parenting skills. If I leave it in the bathroom he'll probably flick through it. I try not to get too involved when he is with the DCs so he can learn to cope with them himself and find his own way. Recently the whole time he has been at home (not much sadly) he has just complained about how the kids are a PITA. They really aren't that bad, just normal for their age. I don't think it is very nice to sit and hear your dad moan about how his life has suffered now he has them (wtf????). They are wonderful kids and he agrees but sometimes he gets into this silly attitude for weeks. Really thinks he needs to grow up and listen to himself.
haven't had chance to read this through so hope it all makes sense.
