Oh, the drama that the lifestyle and humans bring to the table. head bang
My suggestion...ask yourself..is this relationship with this other person/couples healthy to you or the bond between you and your boyfriend.
If it is not, I suggest the two of you discuss it and come to the conclusion to either communicate with this couple and work it out. Or, break off the relationship with the other couple. You can do this in a mature manner.
If you feel it is healthy to deal with the drama...be my guest. After the first incident, there wouldn't be a second, but I am a bit of a hard ass when it comes to people who are in the lifestyle and can't behave as mature adults.
That's just my opinion..take it or leave it. But enjoy life to it's fullest.
Yours in the lifestyle..
