Gift her the ultimate openness in our relationship; that is, the absence of one.
Tell her she can have an open relationship with the door. You don’t get the stability of a relationship while riding the cock carousel.
Her friends. She wanted it
You either agree or break up, not real complicated
Do some soul searching. Are you okay with another dude plowing your field? Maybe you have good prospects and the idea of seeing other women with a safety net sounds like a good plan. If you’re anything like me, this is where the relationship dies.
If you brow beat her into staying faithful she won’t be happy and you won’t trust her not to cheat. So why put off the inevitable betrayal and just get started on your new life.
