Help! Worst argument with husband ever...

My husband and I have been married over 5 years now and have know each other / dated for over 10. The past month has been hard, extremely hard. I husband keeps pointing the figure at me and any other time if it is my fault I will take responsibility and we move on. However, I am 100% certain this is not my doing. He has been unbelievably negative, rude, verbally aggressive, short tempered, and sensetive. Money is fine, family is fine, work is fine. I have pnomonia and have had it 2 weeks now so I am not able to give my 110% with everything and was actually admitted a few days because of not being able to breathe and somehow he managed to be a jerk about that as well. "Oh you just have to make this all about you don't you?" "Ok I guess I'll be the only one who parents around here" stuff like that. Talking to him doesn't help he flips out and says it's MY negativity that is making him this way and that he is not being negative at all just responding to mine. Mind you I'm not being negative! Slow and sick yes but negative no. I don't know what to do or how to get through to him. And God forbid I recommend he see a doc for depression or something. I just can't take it anymore especially with 3 kids and being super sick. He is freaking the kids out too! Suggestions???
