I don’t think it really matters what we think on PC. What matters what you think.
Of course many things are cultural. I think I misunderstood you that her talking to single guys was an issue and was something bothering you. It sounds like it’s not a concern for you at all. I am not sure why you brought it up if it’s no big deal but again maybe I misread it.
I am happy to hear that things are good now and you are content and happy with your wife in your marriage. It’s excellent.
