I am glad that I stumbled upon this thread. I am a mono and my friend is in a poly relationship with a live-in primary. The friend and I have reconnected after a year or so and I was surprised and a bit skeptical about his one-sided definition of his poly relationship (he's was known to me as a serial lover before).
However, after meeting his primary and finding we have many things in common and get along with each other (she directed me to this site), I feel that this may be the beginning of a great V relationship. I still have questions about the whole mono/poly thing, especially time management, but as I haven't really entered into the relationship as of yet (he just asked me today if I was interested), I'm not too concerned or in a rush.
But I feel positive. Thanks again for the wonderful insight.
