Significant other

Does anyone else have a significant other that acts like they know how to do nothing? That acts so fucking stupid that it drives them insane? Mine acts like he doesn’t know anything. Like he didn’t know he wasn’t supposed to abuse me or get stuff out of our money range. Today he sent me over the edge saying he didn’t know how to make oatmeal. Like wtf it’s not that hard. How did he get through life. He’s a fucking asshole. “I don’t know how to change our daughter” “I didn’t know I had to feed her”. I’m seriously done.
