I have only read the first two pages of this thread, and the last, so perhaps I’m going to say something that was already covered.
When you’re out with a woman who becomes obsessed with other men, that’s a clear yellow flag. It’s a problem, 100%.
What’s throwing a lot of people off here is the word, “lustfully”. Each person’s personal definition of that word colors his or her response to the OP.
Some women, while out with their man, become irresistibly fascinated by other men while they are out and about together. These women will find themselves constantly looking over at that other man because they have developed an emotional attachment, a fascination. That man over there becomes the focal point of her evening, eclipsing everything.
Men will often describe that as “lust”, because men will usually look at other women on a surface, physical level. However, women usually look not only at the physical, but their minds start filling in the blanks and they end up developing an entire imaginary dossier on the guy. It becomes a fascination.
Women today are incredibly blind to their own lack of social propriety. If you call them out on repeatedly gazing at a particular man while you are both out together, they will be flabbergasted and vehemently deny, even though they are factually in the wrong and behaving rudely with their man, and insulting both him and their established relationship.
If anyone has a woman like that, I feel sorry for him. There is no cure. She will not be reasoned with, snd she will blame you for being “insecure”. Women today are a horror show of impropriety.
There is only one hope for correction of a woman like this. It’s a Hail Mary pass, but it can work. Tell her to get up, walk with her over to the subject of her fascination, and tell him that she has been looking at him all night, and you thought it would be appropriate to introduce her to you. Then say “This is Name. And you are…?”
If your relationship survives her initial embarrassment and anger, she will likely develop the wherewithal to control her roving eye in the future.
A woman of class resists constantly looking at other men out of respect for her man. Nothing less is acceptable. If my wife did this on the regular, I would have booted her a long time ago.
Burping is a natural human function, but out of politeness and respect we don’t just burp right out loud every time the urge comes. We do it silently snd appropriately so as not to offend. There is a parallel here. If women can exercise social graces regarding burping, they certainly should be able to do the same with controlling their wandering eyes when out on a date with their man. They are not just looking. They are constructing a story about him. They are investing emotionally. They would swear up and down this isn’t true, but it is.
