yesterday was our first dry run with this. I kept my mask on for the sae thinking you had- kept mine on since ds2 had to. But, I don't think he really cares what I do and would be totally fine if I took it off. I do put mine on if I am around kids in close proximity (I worked a yard sale and had to interact with littles exchanging money, talking about items). But, if we were just hanging out in the yard, mask would be off (and I have been doing that for a long time).
I think your dh's travel isn't really a big issue. If he is vaccinated, he is really a lot less likely to transmit it. I think that there just has to be a line where there could be some risks but they aren't worth wearing a mask full time around each other for.
