It seems so simple really - if you want non-monogamy but are afraid of what might happen to your primary relationship, why not discuss and set boundaries that make the things you’re afraid of less likely to happen? The benefits are manifold - you break your fears wide open (airing fears makes them less scary, after all), you set a solid framework of communication with your partner(s) and you get happy, honest sex with all parties.
And jealousy - why, it’s not one monolithic emotion! It’s a tangled mess of emotions that can be coaxed out and worked out one by one. I can’t say it nearly as eloquently as Greta Christina at Blowfish Blogs, so go… right now… and read it yourself.
