Integrity

How do I define cheating in my non-monogamous relationship?

I am a 22yo male wolf in a polyamorous triad with two wonderful mates, a 19yo male fox and a 24yo female vixen. We all identify as bisexual. Lately, we’ve dealt with some infidelity problems, and we’ve been able to work through it, but I think we’re all a little confused about expectations given that we are in a non-monogamous relationship. How should we define what cheating is, given that we have more than one mate as it is?

What is the right thing to do when considering intimacy with someone who might be mated?

Yesterday morning I read an article about a woman who'd enabled a man to cheat on his girlfriend, and when the woman told the girlfriend about it, her reward was to be bitched out for it. On one level, I would say the reaction is somewhat understandable, but at the same time, it's illogical since the woman didn't know the man even had a GF at the time. In any event, the woman has since adopted the perspective that whether the guys she sleeps with are taken is not her business to know; rather, it's their business to tell her. I went in expecting not to be too thrilled with the piece, but ultimately I by and large agree with her conclusions. What do you think about it?
