I'll start with "R", though he is my lover and not my Husband, his relationship has been around longer.
R is my best-friend, well one of them, I have two. (Just noticed that I'm poly there too LOL)
I have known him since 1999, we became friends in 2000, we first kissed in 2002, first had sex in 2004. We dated a few times, but he had, and has, a girlfriend. About a year ago, we started seeing each other romantically again, and this is the longest we have been involved.
I hate that he has a GF - she doesn't explicitly know about me, I'm "the other woman", he's cheating on her with me. I hate it, but I love him and I love being together when we are.
More on this later.
