From reading G_d's Word, I don't believe that poly is meant for everyone....
I have read on this forum, (over and over), that the first wife needs to submit, quit rebelling, and so on. There are those of us that took our vows on our wedding day, with no intentions of straying from them. Have some made mistakes and strayed from the vows? Yes, (me included unfortunately), but the vows were made "until death do us part", not "until you mess up", or "I changed my mind/beliefs", or "I get tired of you".
I had a dream a long time ago about foundations. I was in a house and the walls were not nailed, the floor was sloping and buckled because it was just propped up, and the plumbing was just sort of stuck together. This dream made me look into "Leadership." I learned a number of things.
1. Leaders sometimes take the lead and others follow them. Other times, leaders are made by those whom they lead. They have to make mistakes, they have to struggle, and they have to find a wide range of responses to their leadership style - from those they lead. Those responses must range from fury, to acceptance, to anger, to love, to dismissal, to every other emotion they can find. After all, those who follow are what make a leader, a leader. A leader who does not have followers, is not a leader - He's just a person who is alone.
2. Most men have no idea what the hell they are doing. They couldn't lead a basketball downhill. Especially when they are younger. They are more interested in what she looks like nekked than they are in what the family is going to do ten years down the road. I've met or talked to literally hundreds of poly families, and thousands of those who were interested in the lifestyle. (Been involved in this since 1991) I've seen the best of them, and the worst. No, really, the absolute worst. (Thanks Sean - Joy never deserved that) And from my personal experience, I offer some advice. Ladies, it's really up to you. It's up to him, as well, but a proper leader is created, and you are the one who creates him.
3. "I follow him until he does something I don't like." No, you don't. If you follow him when you agree with him, and turn on him when you disagree, then you are the leader and are fighting him for control. If you stub up every time he does something you don't like, then you are not following him, and he is not your leader. You lead yourself, and you pretend he leads you, and when conflict happens, you rip the family apart by the seams. I read about another one that did that this morning, on here. Older post, but still legitimate. Your JOB, is to teach him to lead, not lead for him. You offer criticism, you offer advice, you stand your ground on occasion, But you do it as someone who needs a strong leader, teaching, helping, consoling, yelling at stupid choices, offering your advice, and offering your skills. You want a strong leader? Saying, "He didn't do it like I want it done, so I'm going to do it myself," is the end of him. You strip his confidence, you steal his abilities and you undermine his strength. You WILL end up with a useless husk you can easily walk all over, right up until you realize you're bored, sick of him, and leave him. I've seen this so much, so so so so so much.
4. Men, she is not your damned slave. Submit is a military term for a person with talents, skills and abilities to willingly agree to let you lead them. If you are not taking that trust, and it is a trust, and making every inch of it all it can be, then you have failed her, and failed yourself. In MY case, it's school, education, talents, and abilities. I built my wife a business, then handed her the keys. I offer her support when she asks for it, guidance when she needs it, and occasionally a bit of a yell when she's screwing up... not fixing the problem for her but helping her to fix it herself. To fix it for her undermines her authority, and breaks her confidence.
5. Vows when you marry define your marriage. What you vow, is BINDING. Both because it was done in front of witnesses, and because she is building her life on the foundation of that vow. So, did God call someone to break their freely made vow? Have you ever seem that in the Bible? Then break it and renegotiate the marriage. Changing it is the same as ripping her world out from under her. Changing the terms of her agreement, abandoning your part of it, and then expecting her to renegotiate with you on it, is not good. You deny her as a person, a real live being, and see her as your subject, not as an equal who pledged herself to you. As her leader, you can negate a vow she makes, but only at the moment you first head about it - that's leadership and protecting the family - a job she hired you to do.
Now, no hate mail please, This is my opinion. It is based on about 36 years of experience, but it's still my opinion.
