I also agree with keeping swinging friends off your Facebook list. We've added two couples that we've played with on Facebook and it was fun while we were all playing. Now that we don't play with them anymore there is just no point in having them on there anymore since we also don't hang out socially. It seemed like a great idea at the time, but it is something we won't do in the future.
I also hate being bullshitted and I much prefer everyone be completely up front and honest about what is going on. Unfortunately that happens very rarely, even amongst swingers who are, hopefully, more open with communication. I think it's a bit over the top to be quite that upset about the situation. You said yourself that the lady of the couple did some things that made this seem quite 'in character' for her; regardless of what people say they are going to do what comes with their nature. I can't tell you how many people we see with adamant displays of "We hate drama" that are obviously serious drama queens. It is to the point now that if I see someone comment that they hate drama, or want drama free people...we don't even contact them. That is a bit of an aside though lol, for your situation I would be glad that we'd gotten this out in the air. I go with my gut and if I suspected they weren't being totally honest and they didn't come clean after some polite and gentle prodding....well, I would be glad to not have to deal with them anymore. I would much prefer to have people involved in my life who are going to be up front with me, so when people show me they can't be I am appreciative that I figured that out. It lets me either know what to expect, or free's me up to move on. Life's too short to have people around who don't make life more fun!
I might be off base with this last part, but under the covers of this post I wonder if you aren't showing signs that you want couples you play with to be exclusive with you, even if it's not something you ever bring up or ask of them. There seems to be a hint of resentment not just that they are now playing with a couple you don't like, but that perhaps that they may have been playing with others while playing with you as well. Of the couples that we played with who were on our facebook, there was flirting on there with other couples and singles that made it obvious to us they were playing with other people. It didn't bother us in the least....in fact we started getting ideas of hoping they might setup a party sometime lol (while we were still playing with them anyway!). It's not a bad thing to want a couple to be only playing with you; I am just wondering if that is how you're feeling and maybe don't realize it? As I said, I could be way off base there; just throwing it out in the open
