I never married nor had children. i have friendships that date back to the 1980s and 1990s, but those friends moved away from where I live. Two of them have spouses, children and grandchildren. When you get into your 60s, it is very hard to make deep friendships of the kind where you can call that person in the middle of the night when you are dealing with anxiety, for example. I keep active in a pickleball league and a fiber arts group, but again, those folks are almost all married with children and grandchildren. We are friendly, but they aren't going to become true friends. Even the next door neighbor who went to the ER with me 2 summers ago and spent the night there while I was taken care of, now has taken a full-time job in addition to tutoring and raising a teenager and has no free time for friendship activities.
