I wholeheartedly agree with
@FollowingHim. You
do fit in here. FollowingHim makes the excellent point that you have been called to reach out to us and allow us to reach back to greet you with welcoming arms. The other great point was that our primary connection is that we're all Christian, with practicing and supporting Biblical polygamy being a strong second connection. Be prepared, though, to discover one of the widest ranges of
approaches to Christianity that you could probably ever find -- because the polygamy is the glue that bonds us together despite the breadth of our doctrinal differences. As such, though -- and it is why I have been spending so much time here communicating with people (and why I consider the conferences/retreats to be golden) -- what is available to you here at Biblical Families is one of the best living examples of how each individual Christian is part of the Body of Christ. He is our Head, but we each have our interconnected part to play.
I also come from a background of secular polyamory (not to mention the "serial polygamy" of successive marriages). As a young man I embraced the Open Marriage concept -- until I watched one marriage after another go down in flames. The more 'modern' polyamory movement is apparently designed to prevent some of the pitfalls of Open Marriage, but it only does so by making commitment a much more superficial endeavor. Others here have already mentioned to you,
@Chesapeake, that the polyamory community is only superficially open-minded. As part of my own search for someone to join my wife and me, I have spent (and, admittedly, probably wasted) a good deal of time over the past several years at OK Cupid and other dating sites where a large percentage of the people are there to make polyamory connections. Being someone who is looking for a polygamous relationship that is not only committed for the long haul but operates within the guidelines of Scripture very clearly presents me to almost all the polyamorists as A Problem. Many of them have some strong level of commitment to their primary partner, but they, almost to a person, avoid becoming committed to their additional sexual partners like the plague. So it puts anyone seeking Biblical polygamy between a rock and a hard place. Most of the Christians condemn us as immoral perverts, but the 'mainstream' polyamorists, in addition to being averse to additional commitment, just lump us in with all the Christians who have ever condemned
them. In general, they aren't even open to creating friendships, much less considering the possibility of being able to experience expanded familial passion and bonding with Christians looking for permanence.
Having said all that, again, I welcome you here. Be prepared, though, for heartache as well as the joy of community. I'm sure I'm not telling you anything you haven't already considered, but by pursuing learning about Biblical polygamy you are likely seriously risking dissolution of your relationship with your boyfriend. In addition, you've hit the nail on the head as far as how much easier it is to find polyamory circles than it is to find supporters of polygamy. For whatever reason, it is a typical pattern for participants in progressive lifestyles to shun those who aren't True Believers, so be prepared for your polyamory friends to shut you out as they get a whiff of what you may begin to consider as you learn more about Biblical polygamy -- and it can be daunting to contemplate being on the outside of a subculture one was previously immersed in. I will join the chorus, though, of all the others who have welcomed you here and who have encouraged you to participate in the weekly women's chat. We're all just human beings here -- so we have our own foibles -- but I trust you will discover that there are many very good people at Biblical Families.
You've come to the right place!
