[Look, they still had to clear that up.]

Hey, you don't really know if it will. If anything does make your friendship weird, it's not saying anything. You're probably acting odd around them right now, and that could confuse them - hell, it might even hurt their feelings since you are different around them only. If you guys are friends, you should be able to be honest with them.
