So of late I've really improved my game and am easily picking up at least one girl when I go out. I do have however one girl I've been having sex with weekly for a while, i like her and don't want that fuck buddy to end but I obviously also love going for new girls. This week my fraternity has a date party and I'm taking someone other than said fuck buddy and I'm sure there will be pictures on Facebook of us, I'm sure fuck buddy will at least ask about why I didn't take her, in reality shell probably be pissed even though I've said to her I don't want a relationship. How should I respond?
