It's always awkward when you're walking down the street with the guy you love most, and you see his ex girlfriend in a picture in the window of a store in town. Literally.
It's not awkward in the "I don't know what to say" way, but in the way that we both, for that split second, are thinking of how life was when he was with her. I don't think it's jealousy, just anguish; the fact that my whole life wasn't spent with this guy, that some of his amazingness was shared with her at a point in time. Maybe I am jealous? I shouldn't be, he's mine forever now, we promised.
I hate how something so small can make a nice thing feel weird.
