I think, although this pandemic has brought out the best in a lot of people, it's also brought out or produced cracks in marriages.
Spending all your time being cooped up with anyone, be it husband, wife, kids, without the normal day separations of work, hobbies, meeting friends etc, must put a strain on many relationships.
Alternatively, for some it's brought them closer together....people have had no choice but to interact a lot more with each other.
However it's sad that there is a 50 year record high number of divorces now.
