Hmmm I think things like this should be discussed AHEAD OF TIME not after... but too late for that now...
He would really like to do this and I feel that he is basically telling me that I don't satisfy him and he wants to be with someone else.
that's a pretty harsh view of yourself and your relationship ... you FEEL this but you don't KNOW this... this is something that needs to be discussed. Ask him what his motivations are... ask him lots and lots of questions... make sure he knows your feelings on these subjects too.
What happens if doing this wrecks our friendship with these people
Well that happens... a lot of people, myself included learn that the hard way... and from that point choose to make friends among swingers rather than swinging partners of friends. Sometimes it works out... but you can't know that in advance.
good luck...
