So I have a girlfriend who lives about an hour away in her hometown. I'm in college and she used to live with me in an apartment, along with three other roommates, who also came from her hometown. Her sister currently lives with me, as well as her best friend, and a guy and his girlfriend. They've all known each other for years as they grew up together. Her sister is just ok, but her best friend and the guy's girlfriend are really cute. Best friend perceives herself to be 9 (imo she's more like an 8 ); she has had a fwb with a guy in a relationship before. She currently has a "relationship" with a guy, but the guy isn't her "boyfriend" because they don't want to put a label on it; aka another fwb. she's rarely at home. guys girlfriend is most likely an 8. I have constant and consistent very friendly day to day interactions with her, as her bf usually spends all day in his room playing video games. They don't even sleep in the same room. Would I be able to have an affair with any of these two?
