My SO won’t stay his ass home

I had to go to my grandparents (I am their sole caretaker) I took my newborns with me because I didn’t know where my SO was so when I get back he’s still not back so I ask where he is and with attitude he says “you’re out and about so I went to my friends house”

Ps: I go to my grandparents every night at the same time so he knew where I was. I wish he took this quarantine more seriously. My town is under lockdown. No going out unless you need meds or food. And his ass STAYS in Walmart then comes home and cuddles with our babes. I’m about to go stay with my mom, I swear.
