my oh and i are gonna really fall out

if he carrys on the way he is. sorry i really need to get this off my chest before i explode. dont get me wrong my oh is a great, hands on dad and a wonderful partner BUT for the past two months he has been driving me up the wall with his nit picking. it ranges from "oh you should of done it like this "or "well i wouldnt of done it like that" to "why havent you put the dishes away "(hello i cooked diner and washed up and got our son to bed while you were reading our daughter a story and is he unable to put the dishes away himself). and the list goes on. i have now got to the point where i feel that we are no longer a team when it comes to our children cos if anything goes wrong (ie one of the children start to play up) that it is my fault coz i should of dont it this way. i have talked to him and broken down in tears telling him how i feel but it just feels like it is falling on deaf ears. now i find that i just walk away feeling like the wrost parent/ partner alive when he starts nit picking coz i just dont know what to do. ?
