Re: communication ... do you know specifically what you'd like to talk to them about, or are you just feeling confused in general, and wondering what to say to them? Communication is certainly one of the most important parts of a relationship, especially if it's a poly relationship.
How do you feel about the emotional limitations on your relationship with her husband? Sometimes it's quite difficult to keep things casual.
Anyway, I hope Polyamory.com is enjoyable and of help to you.
Love means never having to say, "Put down that meat cleaver!"
