The difference between Poligamy or Monogamy and Open Relationship, is that the last one is not something established by the society, culture or system. It's a personal choice. If I find someone who I develop a strong connection with and compatibility and both of us decide that we would like to keep our independency while still having some commitment with each other, what the society has to do with that? I'm glad I can make my own choices without being influenced by what people expect.

As I keep repeating, open relationship is a personal choice. It's not for everybody. But everybody who decides to engage in that has the right to do so. If you think it doesn't work, that you'll be jealous, feel rejected, or feeling you'll go around hooking up with anyone, don't engage in one. It's clearly not for you. Simply like that!

Is that the right way to demonstrate love? There are better ways I think!

All forms of love is valid, whether setting the person free or restricting him or her for you... Whatever your hearts want to go... ;)
