My fiance might have covid 19

My fiance is an essential worker and is the only one who goes out of the house. I'm 20 weeks pregnant and have a 3 year old. We stay inside and don't even go to the store, my fiance does that for us.

He's at work right now and just texted me saying he has a slight scratchy throat and a cough. He made a point to say it's very minor. But the reality is I've really just been waiting for the day he gets it.

I don't want to get sick, I am an at risk person and if I get covid 19 and the symptoms fully develop, I will be checking myself into a hospital for the sake of me and the baby.

Obviously I dont want to do that... my fiance would at least get to stay home for a 14 day paid sick leave and take care of our 3 year old while I'm in the hospital. I'd probably just have to check myself out of the hospital after those 14 days though, otherwise the only place they could go while my fiance is at work is with their very irresponsible grandparents.

It almost seems impossible for me to not get sick if my fiance is sick. Even if I dont touch my face and wash my hands frequently, even if I never touched him which would be very hard to do. My sweet little one couldnt even touch their daddy. I think it's just inevitable...
