This is an interesting topic, I've been trying to figure it out for myself. :)

In general, I think that jealousy is not a good, beneficial feeling and it seems like people do some bad stuff out of jealousy - gossip, verbal or even physical coflicts, bullying...

When it comes to relationships, I've definitely experienced jealousy but I'm not about drama or making a scene. I'm also not about controling or treating someone like it's my possession, same way I don't want to be treated that way.

In my opinion, when there is communication, honesty, respect and dedication to each other, there is no room left for jealousy. Another opinion of mine is that people often get into relationships thinking that way they will be "completed" - we need to be happy and comfortable with ourselves first, not expecting from other person to make us happy. With that said, I don't think I would be able to be in such an open relationship that would occasionally involve a third person. :D

Loved reading your thoughts about this topic! :)
