I have been in a monogamous relationship with my bisexual girlfriend for the past six months. We've recently been discussing incorporating threesomes so that she can further explore her female-female side, and we are both feeling pretty confident about doing so. However, today, when we were talking about this, she brought up that she had been thinking about her best friend (female) who she sometimes thinks about in a physical manner. This is the first time she admitted this to me, but it was pretty obvious to me already. When I'm with them, and sense that it's a bit more than just a friendship. The thing is that they have been intimate in the past, and so her liking her friend in that manner seems more complicated and more serious than anything like a threesome. Her flirting with this friend makes me feel uncomfortable, and I'm not sure how to handle it. She hasn't done anything with her, and so I'm not really upset. I'm just uncomfortable with the situation, and I don't know what we could do to make it better. I don't have a solution, and me feeling uncomfortable is kind of driving her mad since she insists that I come first and that they haven't done anything together. Any advice?
