Family problems

I work graves and my wife works days we have a son 2 years old and I take care of him during the day while my wife works , it is hard for me to watch our son and go to work at night plus my wife is stressed out from her job when she gets home so you could say that she brings her work home , so we now have problems at home it seems she is none tollerant when I dont do the house work or about any small matter that occures at home so much so that she screams and yells at me which is unlike her , she has enven threaten divorce. and when I mention that she is under stress because of her job she then says that what I really want is for her to stay home and not work which is not true , what can I do ?

i think you, your wife and your son should all go on holiday. a few nights of rest would be brilliant. you dont have to go abroad even just take a few days off and relax. your wife needs a rest by the sounds of it.
