Does it make sense that my dad is hurt because I don't want anyone too close to my toddlers during this pandemic?

He's retired, living with my mom who works with covid patients sometimes. I think he has become depressed... because at first he said he respects me as a parent and understands the social distancing. Then a few days ago, he tried to convince me to see the kids in a "normal way" (no masks, close contact). I said not yet. Now he's hurt and won't speak to me or acknowledge me in any way. My mom is on my side and talks to me. I just visited her today at a distance but my dad didn't want to come out. The other grandparents understand me.

I think the isolation among his retirement has shot his mental health. I've never "seen" this in him before. I don't wanna straight up be angry with him. I'm not taking it personally as he is. Idk I feel like he just has to deal with this. *shrug*
