is this healthy?!

i have a newborn, and it’s our first kid so my man is a literal psychopath about germs and taking our baby anywhere. i have lots of nieces and nephews so this isn’t new to me, and i know a little hand washing goes a long way. anyways, he has been off work since we had our baby and we haven’t gone many places as a trio, if he does let me and baby come anywhere we stay in the car. but he goes anywhere and everywhere with his friends and leaves me at home alone with the baby. at the least once a week but typically 2-3 times a week. today his cousin called and was upset and asked if we could hang out with him so he says yeah sure we’ll go to lunch i’ll come pick you up so i start getting dressed and he says oh you and bubba are coming? and i said yeah why would we not i’m hungry too? and he said never mind i’m not gonna go then i didnt wanna go anyways so i just said okay whatever we’ll stay home i guess so we fought and argued for a few bc i’m tired of him leaving me here with NO CAR and then he left. so i’m like when’s the last time i even left the house?! SIXTEEN DAYS. it’s been SIXTEEN DAYS since i left my home. this is so unhealthy mentally. i’m probably just being crazy bc i’m riddled with PPD but now i’m wondering if he’s even been doing what he says he’s doing and maybe he’s cheating.

i plan on confronting him when he gets home about constantly doing whatever he wants but keeping me a prisoner in his home, but what do i even say? advice would be appreciated
