I'm not going to attend my kids' sports games
Why aren't you going to their games?
I keep some distance from my children as this is the only way I can keep them safe.
Wanting to keep your children safe is understandable but you should do your best to support them. If you don't go to their events they will feel you don't care about them.
It's fine. Kids are resilient. They'll be fine without me.
You might think that they'll be fine, but they'll feel more loved and supported if you go to their sports events. Unless your presence causes them imminent threat, you should let them know you support them by being there, even if you don't think they care.
