Your SO is treating everyone friendly, but doesn't go out of their way for most people. But you can have any comfort. Even if it sometimes means that you are treated better than your mutual friends while hanging out together. Especially if we're talking about money. Like your SO will pay for everything you want, but your mutual friends, who might not have as much money, don't get the same treatment, even if your SO could easily pay for them as well.
Would you accept that treatment or would you prefer your SO to scale down the treatment of you? Or do you do something else?
