When I got married to Rose like most people, I vowed to her that I would forsake all other women besides her. Of course, if I had known the truth about polygyny, I hope I wouldn't have made such a vow, but who knows. When I discovered the truth about polygyny it didn't do much about it, but every once in a while, I would bring it up and explain the truth about it. I didn't say I wanted it for myself, but I was trying to prepare the way.
Honestly, I didn't think I could ever bring myself to telling my wife that I wanted to marry another woman. I loved her and we had a great marriage, and I didn't want to lose that. A few years later I decided that I was going to tell her that I wanted another wife. Before I did that, I prepared a Bible study for her that was about 20 pages long, which became the foundation to the book I'm writing. The approach I took was that I would honor my vow to her unless she voluntarily relesed me from that vow. I'm not saying that I had to do that Biblically speaking, it's just what I decided I was going to do.
My wife is a believer who strives to live by the Word, so I knew that the only way I could get her to release me from my vow, was to prove it was Biblical. There were some tense moments, some fireworks and she later told me that she thought about leaving me, but in the end, she willingly released me from my vow. Of course, this didn't happen overnight, it probably took a good year or more.
I'm not saying my approach is the best, but thankfully God blessed it. At the time I thought convincing my wife would be the hardest part, but I was definitely wrong about that. Finding wife number two has been much more difficult! Thankfully, polygyny has actually brought my wife and I closer than ever to each other. There have even been times when I thought about giving up and she has talked me out of quitting. I think one of the things that helped my wife was a couple times the woman we were talking to tried to get me to leave my wife for them and that wasn't going to happen even if hell did freeze over. Now that I'm 52 the thought that polygyny may not become reality for us comes to mind more often than before, but either way Rose is a keeper, and she still makes me very happy.
