When you're willing to throw your 'loving relationship' under a bus because your partner got insecure and jealous, and you'll save that relationship before insisting on equal respect--that's an 'open relationship,' not 'equal loving relationships...'
Make sure they know upfront that they are expendable, and therefore ultimately an entertainment.
I think that last sentence is quite harsh, and at first, I just started replying based on my reaction to that sentence. I will come back to that because I think it needs to be addressed.
After I started to reply to that last sentence, I went back and reread, and I saw the former paragraph. I would tend to agree with you. What you described is not equal and loving, at all. I would loathe to treat either of my partners (husband or other partner) that way, but just because one's priorities are different than yours are does not mean that their other partners are "expendable" and "an entertainment" to them.
My poly doesn't have to look like your poly, and just because I do put my family before my other partner does not mean that I consider him expendable nor an entertainment. I would never just drop him because my husband had a change of heart, but if that change of heart happened, then serious discussions would have to happen with everyone to resolve the situation because I do care about him and his feelings and have feelings of my own that matter, as well.
