I was checking the recent views of my OKC profile and one guy looked familiar. I checked his profile and sure enough...my friend's boyfriend! I'm pretty sure she knows because they are in a poly relationship. Maybe he clicked my profile because I looked familiar, but that was definitely a surprise.
Not yet. I will see her tomorrow and mention it. I won't be surprised if she knows because she is poly, as is he. And he even mentions in his profile about being poly.
