Wanting self care time without partner. Is it just me?

So I am a mom of a 3 year old & to a fur baby of 10 month old dog. After cleaning throughout the day multiple times, taking care of them, spending time with them, & cooking I am exhausted by the end of the day & just want time to myself when my little one is asleep. Her daddy wants me to lay/cuddle with him every night. It gets annoying. I don't ever have my me time. Nothing against him but I just feel like I'm gonna go insane if I don't take care of myself when I have the chance. I do work 4 days out of the week & I am just tired. I know he doesn't understand & I know I probably hurt his feelings when I tell him I want time to myself like tonight. I don't know how to get him to understand that. Anyone else feel this way?
