Just wondering

I'm just trying to figure out if I'm tripping or not. Ok here we go I'm a stay at home mom my SO works we have 3 kids between the ages of 4-9 but when he comes home he goes straight to the garage to have him some time to his self now I wouldn't care if it was like an hour just to relax but it's like all night so he doesn't spend any time with me or the kids and I never get time to relax I feel like he thinks because he makes the money that he shouldn't have to do anything at home am I being petty
