Honestly I don’t even know what answers I need here?

My wife and I recently started dating and amazing woman she always described herself as a unicorn at heart always running free and not tied down. So when we started it was simply supposed to be a lot of fun. Recently things have changed we spend almost every day together at lunch and 2 to 3 night a week when we can. She calls us her bf/gf and it’s become something more. However the issue/situation came up about her hooking up with others and other couples.

I’m just having some issues I guess. Because for her it sounds like she wants and open relationship to just go do anything she wants but at the same time wants us as primary partners for the emotionally and romantic needs of a relationship.

I know I rambling but I’m so twisted in my mind i almost don’t know which way is up. If we are dating I would think that playing with other would involve us as well but maybe I’m wrong would love some additional thoughts or advice if anyone has any?
