My W goes and hangs with her women friends a couple times a month. They are MARRIED and they hang out at one of their houes and talk about books, drink some wine and do the 'girl stuff'.
They do NOT go out to bars, and there are NO single women. No married woman should go to a bar with single women without her husband. The MEN at those places are there for one reason.
My point is that there are many ways to 'hang out with the girls'. Go out to dinner, movies, book clubs, 'bunko' games.
