Would you care if you're bf/gf hung out with someone of the opposite sex? I've been with my gf for 3 months now, and she recently told me that she doesn't feel comfortable with me hanging out 1 on 1 with a female friend of mine. It's strictly a platonic relationship with this female, but we did sleep with each other over a year ago. She also stays overnight at my place sometimes. She sleeps on the sofa, while I sleep in my bed. Sometimes her other female friends stay over too, since I have plenty of room at my house. How would you feel if your SO was in this situation?
