I wish you the best of luck. Laying everything out on the table with all parties involved is also an option. I'm not sure if you mentioned if CC had met Peaches yet but sitting everyone down and having lunch or dinner can really help clear the air. Currently my lover V and her husband Mr. E are overcoming a similar situation. It hasn't been easy but very slowly we are all learning how to deal with this blossoming "hinge" relationship and Communication, Communication, Communication has brought us very far. Creating rules and boundaries without everyone at the table may only create more miscommunication and frustration.
