Hello all! I would really like your opinions about my current situation. My poly partner met a girl (non poly) a year ago who had also met another man (non poly) and began and mono relationship with him. They got engaged but recently she has become very unhappy in the relationship, having to sneak in and out just to see my partner. Her and her fiancé are still together. My partner went on a date with her earlier this week and they were intimate, without her fiancé consenting or even knowing about the situation. I do not know how to feel about this as she obviously cheated on her fiance and my partner knew that. What are some opinions on this? And how do I discuss this with my partner?
Thanks!
Thanks!
