Am i wrong about my role in the relationship?

i have been with my fiance for 6 years. We have 3 kids and are generally happy. Today he calls me at work and asks me to look online to see when his court date was...well it was on aug 9th and now there is a warrant issued...when the date was first set i looked it up gave him the date and havent thought about it again. Noe he says it is my fault that he missed it...I am so fed up ...i have 3 kids to remember dr. appts, school functions and all that for and i am supposed to keep track of his things too? I told him i was not his mother or his secretary and if he wanted that then he could go back to livin with his momma...the worst part is he doesnt have (and never has had) a job AND the kids are in daycare all day...if they are sick I CALL IN SICK TO BE WITH THEM!!! Am i wrong to be completely livid at him for blaming this on me ir is it the womans responsibility to keep track of EVERYTING while the man does nothing?
