In my opinion, there is nothing else you need our help with. It seems that you know what you need to do, but the thing is you can only control what YOU do. The other people need to work together WITH you, not AGAINST you or SEPARATELY from you, if they also want this to work for everyone.
It is my suggestion that you switch to a blog thread, because it seems to me that now you are more in talking-to-yourself "journal" mode, rather than seeking advice/discussion mode. For the past few posts you've been see-sawing between "i'm sure monogamy is the only thing for me" and "i think I'm down for a poly relationship between John and Sarah as long as they don't kiss on the lips in public."
It's starting to give me a headache, so my usefulness is at an end in this thread (if it ever began in the first place).
