I’m 69 years old, moved to a small town, and we have female clicks here too at my age!  I no longer let it bother me because there are women friends who like me, and the cliquish ones aren’t women I care much for anyway.  I know LW2’s situation is very different, but she doesn’t need these women who still act like they’re in high school!  Ignore them, have fun and they won’t get satisfaction out of ignoring you.
