Check out my blog www.polyamorouspeople.com
. I started it up for myself to cope with a partner who is polyamorous and found that there are lots of people out there that need help meshing poly and mono. Sometime forums can be daunting for "the stunned" (people whose partners inform them they're polyamorous. My blog seems to help, especially the early posts when I was also struggling.
Good luck, it's a process but it can work.
