I agree with Jane and rory. I think your example of navigating both the traditional relationship issues as well as the more poly-specific relationship issues is very beneficial here. Even the wondering about possibilities can be a great guide to those who think that everything has to be figured out right NOW. I think seeing the process- the wondering, the talking, the waiting- might be VERY helpful to some readers.
And for myself, I like reading for much the same reason as Jane- another (working!) example of my relationship configuration, yay!
