I used to be involved in a few poly relationships with some girls, a few years back. For those of you that don't know, that means, basically, open relationships with multiple people. The girl I'm talking about and I were a part of a tiny poly deal (one other people).
That was my last poly relationship. I was getting tired of sharing. In this case, I'd go a week for a chance to see her, sometimes more. I felt like she wasn't even making an effort to see me like I her. So after a while, I just stopped trying. About a month later I got an E-mail that said, "I think we should break up (short version)?" To which I replied, "Kay." And that was that.
The sex wasn't even worth the effort.
