Easter dinner dilemma

So easter is coming up this weekend and I’m in a bit of a dilemma. My entire side of my family are taking social distancing super seriously, therefore we are not doing a family dinner until this virus thing is done. My boyfriend and father of my children on the other hand is not taking it seriously. His family is still planning a dinner and he is still hanging out with his brother and his friends despite me telling him not to. We have an infant daughter and an 8 year old so I am terrified of them getting sick.

I don’t know what to do about easter dinner because I know that if I stay home with the kids my mother in law will be so offended she will probably never forgive me. But I need to keep my family safe. Also my side of the family is saying they’d never forgive me if I went and one of the kids got sick. So now I feel stuck in the middle. Anyone else going through anything similar right now?
