I just have to say that I am glad that there is a my poly is not your poly thing... I don't think disolving a marriage is the answer nor do I feel like I have to be married. I myself prefer some sort of commitment ceromony by those involved and I think it is unrealistic to expect all partners to be equal at all times...
I don't mind that my GF makes less money than me or that my BF makes 2 as much as me. We all bring something different to the relationship.
