Your situation is very common I think. My wife really struggled this last week. Yesterday, several of my wife’s friends were going through break downs. They do Marco Polo. It helps some.

For my wife, the best thing I can do is take a turn with the kids and let her have mental health time. In your case, I’d suggest that you try to find a time that your wife can go on a walk with her friend (or just meet up and talk) They can start 6 feet apart. You still are being good social distancers but she gets some talk time.
