passive aggressive SO vent

Hannah • Hey my name is Hannah. I am a 27 yo SAHM 💙👶🏻 💙4/29/16 💙👶🏻 💙4/23/18
I have always known my SO is passive aggressive and it never bothered me. Like I would get frustrated we would talk about out then it would sort of fizzle out. Well my son is 9 months and I have a lot of medical issues after giving birth so I need my SO to do a lot more than he has in the past. I have always done 90% of the housework and cooking and baby care etc. But I never minded because I enjoy maintaining our house. Well because of y medical condition there are certain things I can't do comfortable anymore like take out the garbage, sweep, mop and load and unload the dishwasher for starters. Initially my SO was like not a problem I'll take care of it you focus on getting better. Well I notice when I ask him to do certain things e does them but wrong. Like I ask him to load the dishwasher which takes like 5-10 minutes give or take but instead he'll decide to take
Over an hour to wash dishes by hand. I'll ask him to sweep and instead off using the broom he'll use the dustpan to sweep the kitchen taking much longer. I'll ask him to clean the bathroom and instead of using bleach or any other cleaner he'll use Clorox wipes and just wipe things down and not actually scrub anything. When I say something he says well I'm doing it aren't I? At the same time he leaves more of a mess. For example he was eating cereal in bed the other day and I left and came back at night (he works nights) and he left the cereal bowl under the covers still with cereal in it? Or e leaves a hammer and screws out so my 9 month old can reach them. I feel like he's being spiteful. I'm trying not to argue too much with him because of his passive aggression he just always shuts down and it's useless. Anyone have any advice on how to deal with passive aggressive people.
