Crush problem ??

I talk to my crush a lot and he likes me back bc we flirt and call each other cute, send “x” ect. Anyway, sometimes we don’t talk at all. We don’t talk for a day until I message him saying “I miss you” and he’ll respond but that’s it. He’s going through a lot atm with his Mum having cancer and his dad having stomach problems so I understand that might want to spend time away from social media and spend time with family but if it’s not that, what could it be? I asked him if he was talking to other girls and he said no so I believe him but he can go a day without talking to me but can still view my story and shit on Snapchat? Idk what to do ://
