Hi. There is a scripture verse somewhere. catholic bible version Sirach 42:11a, 12-13. This wisdom book forbids single women hanging out with married women. "Keep a close watch on your daughter, lest she make you the sport of your enemies. vs. 12 Let her not parade her charms before men, or spend her time with married women; vs 13 for just as moths come from garments, so harm to women comes from women. I think this is true. 2 is company 3 is a crowd. married couples with each other is fine. She does not feel threatened about her husband around other married couples but in the back of a married women's mind is the threat a single woman is to their marriage. I hope this makes sense to you. Get your book back, start a singles group only for bible study. Leave the married people out of it. Blessings.
