How social he is (or isn’t)
You may have learned just how much of an extrovert or introvert your partner is during this. Ironically, if your partner is an introvert and conforms to what studies have shown, he may not be thriving the way many expected introverts to do during this time. He may be even lonelier because introverts are less likely than extroverts to stay in touch with loved ones via phone calls and video chats. Maybe your partner claimed he was an extrovert, and now you see how quickly he gives up on talking to friends in the pandemic. Maybe he said he was an introvert, but you now watch him go out of his way to keep Zoom hangouts on his schedule with buddies.
