lago24 - in order for a polyamorous relationship to work...both partners need to be prepared to relinquish all jealousy and possessiveness. Ideally both partners know ahead of time before making a committment with each other. If you're not willing to do this, then it's not really fair for your wife to spring this on you. If you not willing to go with this, then you should make it clear this isn't for you. If you both end up leading this lifestyle, make sure you practice safe sex and be honest with the people you get involved with. If this whole idea of your wife being with another man instills a fire in you, then this definitely won't work and you should speak up.
