Welcome to our forum.
It sounds like you identify as polyamorous as an orientation, even if your life situation doesn't match up to it yet. Are there any poly groups not too far from you? For example, if you google "Michigan polyamory" does anything promising turn up?
Anyway, I am glad if Polyamory.com has been helpful to you so far, and hope it will continue to be. Don't hesitate to post any thoughts or questions you want to share.
