Our relationship is the best it's ever been. Sex all the time, anal, cum where I want, Cooks and cleans, she does as I say etc. (also a virgin before me)

She however has brought this certain guy up several times in the past. Told me she deleted his snapchat a while back, then added him back after an argument thinking It would be a power play or something, told her to get out of my house. Hasn't been an issue since.

However she brought him up today again after a while of not hearing about him :

Context: I said something along the lines of "this chick would take me to a free dinner" to which she said "you wouldn't approve of the guy but I could get a free dinner too, double date?" (Hard to paint the picture but she was definitely alluding to him)

It's not too much of a concern too me, however I don't want to hear about said guy again (unlucky me huh, that's not how it works), assume I shouldn't bring it up. Do I take it in stride, re-assess?
