A decision needs to be made about your daughter, i.e., where is she going to stay until the crisis is over. Your h has been around someone and he needs to self isolate. If he's around your daughter, she may need to self isolate as well. She could very well be a carrier and not even realize it. As her mother, you will need to decide, does she stay over there and not come to your home or does she move in w/you until the crisis is over. No one knows if your h will eventually show signs of having the virus or not, but I would be very concerned about you and the children that are living w/you.
kas, please, please be careful and stay safe and well.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
