That’s great that you have time carved out plus a neutral facilitator to help you along. That alone should make a huge difference. If hubs isn’t interested in reading, you can bring up things that you have in the conversation to discuss.

Some of the other good books on the topic other than Opening Up are The Ethical Slut, Building Open Relationships by Dr. Liz Powell, and Eight Things I Wish I’d Known About Polyamory Before I Tried It and Frakked It Up.

Wishing you all the best.
