While maybe not one of our better impulses, wanting to see the ex's eyes bug out when surrounded by a bevy of attractive women doesn't necessarily mean you aren't detached, just means you're human.
Don't overthink this. You need snacks. Go to the store and get some. End of story. If you're W sees you and, a la Homer, thinks to self "Egads, what have I done." Fabulous. If not, dude, you're getting snacks for a road trip with 3 hot coeds. Enjoy yourself my friend.
