Polyamorous relationship

Ok so my girlfriend likes another guy, but doesn't want to end our relationship, she suggested a polyamorous relationship. I am Bi but I don't want a 3 people realationship, so do I tell her no or try it out?

It seems like she suggested that because she likes him and doesn't want to hurt you.
You should just find someone else.

If you don't want a polyamorous relationship, and you know you're not attracted to this other guy, you should probably tell her that you don't want this kind of relationship. It's unlikely your feelings will change once you try it out. Try talkign to her about your feelings. If she insists that its between a polyamorous relationship and you, then you'll have to decide whether you'd rather keep her as a girlfriend and add an additional playmate, or find a new woman/man

I'm sorry, but if she's not satisfied with one person then she shouldn't be seeking anyone. Greedy
