Your responses to me feel very one-sided. I entered this relationship monogamously and she knew she wanted an open-relationship but didn't tell me. I only found out because she cheated on me with someone. That to me is unacceptable. However, I am willing to try this to make her happy, but also not be hurt in the process and still be respectful.
As for some of your other responses you are basically describing a different kind of relationship than we/I want. Im not looking for a relationship where Im just there to give her a place to live while she runs off screwing everyone or we have free roam.
From your responses I take it as though you are the type of person that simply wants to do whatever you want without restriction and consequence. She indicates she wants to have a primary relationship with me. Well a primary relationship whether it be monogamous or open should have boundaries.
