Long Distance: No, this one is out. Open Relationship: This would be the best route if you can get her to swing for it, but you’ve got to be totally chill with the fact that she will be on some strange penis in your absence. Also, the longer you are in an open relationship with her, the less likely you’ll return to monogamy. Once you cross that line, she will start treating you like one option among many, not a special partner.
