Jealously is a beast, that's for sure. My Dom is poly, even though we agreed when we got together that we would be monogamous. It's still hard though, I feel like I phase into the Hulk everytime another female gets within ten feet of him regardless of if he notices her or not.

But like someone else said, you need to figure out where exactly the jealousy comes from before you can work to control it. Mine comes from a few places: 1- the absolute certainty that I'm not enough to hold his interest crops up every so often, 2- pure vanity because he's a tall, hot musician that could have anyone he wants and I'm an overweight short girl with a big mouth and a bitchy attitude. My jealousy comes from my own insecurity, not from things that he does, so I know it's something I have to strangle because he can't help me with it. You just need to find your niche in his life and remember that that place belongs only to you, that no one can take it.

That being said, I have one thing to add about the poly lifestyle. No offense to anyone is meant, so please don't drag me into a proverbial alley and kick my ass. I've been in poly relationships and this is my take on it: the only way it works is if everyone is poly. Eventually, in my experience, if a monogamous person is in a poly situation, it will become too hard to deal and the relationship will have to end. So that's something you need to explore as well, make sure you can handle being one of many. Slave or not, that's still a decision you have to make. Poly is hard, it takes a lot of will to maintain that lifestyle, so make sure you want to put in the time.
