If your wife loves you she will not hold you to a vow that is based on a fraud. If you love your wife you are not going to even consider voiding the marriage
The cultural disenfranchisement aside, this is the other issue that I think I’m seeing clearly with this topic.
How many stories have we heard of wives that recognize and acknowledge the Scriptural truth of poly, and yet refuse to support their husband in any way towards a biblical family model (poly or mono). So often, the first wife is cast as the victim of her husbands new understanding and then the focus is more on soothing her as the victim of vow fraud, and never acknowledging the massive offense that the entire culture has perpetrated against her husband.
If the same situation were cast in the light of a monetary inheritance, most wives would be the first and loudest to decry any party that had perpetrated her husbands disenfranchisement of what is by right his.
Caution!!! You cant unsee this!!!
At what point does the wife become complicit? Obviously not at the ceremony. But what about the point that she recognizes that its a Scripturally valid construct?
