Is Monogamy dead?

For those that don't know the word polyamory combines the Greek word for "many" (poly) and the Latin word for "love" (amor). Are we time travelling back to the days of the Greek gods when before marriage it was grapes, fab wine and fucking around rather than settling down? 

It seems not only is poly relationships thriving IRL but also in Secondlife. Last year I found myself in a poly relationship through Secondlife and personally it was one of the worst mistakes of my life. It was something that felt forced onto me and I didn't know how to get out of it without losing my other half. Eventually my mental health tanked and when I reached the bottom of the well I called it quits. It wasn't for me but it was something I wanted to try for the sake of my partner and their wants without actually considering my own. 

Albeit I've heard people say it is something that has enriched their lives, helped with their emotional intelligence and communication skills. I've seen so many poly relationships work because it's something both partners want, for example, I know one couple who thrive in a poly relationship because they understand the key components to being poly is communication. If you aren't communicating with your partner about who and what you are doing, how you feel about certain people or situations and validating one another's feelings- it isn't going to work out in the long run.

I think because poly wasn't largely accepted Monogamy was rather popular in Secondlife, if you put aside BDSM relationships, though that is a different (future)  topic altogether. But you'd see people with the Mr and Mrs tag before you could change your name. They'd have over the top weddings and celebrate their love by decorating their profile with their soul mate.

Although Mono isn't completely dead (yet) it seems people are more accepting of being open, especially the younger generation, with everything laid out like a buffet they want to try a little bit of everything. 

So I have to ask... Is this the new generation of romance? If you are poly, why? If you are Monogamous, why?

And the real question here is: Which one causes more drama?
