Welcome to our forum.
It is nice to meet you and you gave a good description of yourself. It sounds like you and your husband have done some intense mutual soul-searching to get to where you are now. I hope Polyamory.com will help you to continue with that process. I can imagine it must all seem very overwhelming right now.
Take your time, and just look through some of our threads at your leisure. Post your thoughts, questions, and comments as they arise. Don't try to hurry yourself into the practice of polyamory yet. Give yourself some time to get a little more comfortable with the idea.
It is good to have you aboard.
Love means never having to say, "Put down that meat cleaver!"
