What do you think about non-monogamy?

I wonder anymore what is real and what is attention seeking. So many people use the internet for negative purposes, and one wonders in some cases whether the situation is real or they are creating a scenario for people just to talk about and get themselves known.
That being said, I am about people living their lives as they wish as long as they act within the law and conduct themselves decently, but I also feel relationships can be complex and when you try to flow into these group situations it eventually will erode. So much room for error, and too many feelings to tackle constantly, even if their jealousy levels are low.
