Is my husband a narcissist? Help!

[joesyf]

Desperate - my husband is moody, sulky, manipulative and makes us all walk on eggshells! He walks in and the whole mood changes in the house, he starts ordering the kids round to do jobs, so much so they all hide in their rooms all the time now!! He doesn't control money - instead he leaves it all to me and takes a step back!! Stress!! He doesn't help around the house and states fairly often how he works over 50 hrs per week, I work 30 and have three kids and dog!!
All 3 of my kids complain about him, how moody he is and how they don't like him. He is always right too, which drives me mad. He is rude to my family and friends and we never know if one day he will speak or ignore them, it seems to depend on which way the wind is blowing!!
He is really irritated by everything, he constantly tells me I have no sense of humour when this is the one thing people always praise me for! He criticises my eldest (who isn't his) and they do not get on. I can totally see why he doesn't like my H.
All the kids keep saying if I leave him we will be happy, but we have been together 13 years and it's a long time! Im scared. I've tried writing pros and cons but the cons out weigh the pros by miles.
Help me please x
