My lover-friend and I celebrated our 2-year "unniversary" earlier this year. He is still not my "boyfriend." We are still very happy and very much ethically non-monogamous.
I don't stress as much about definitions and terminology as I did two years ago, but I still find that caring friendships with a sexual component are what work best for me. Serious Romantic Relationships aren't something I seek.
Single, straight, female, solo, non-monogamous.
