YOUR angry? Something tells me this will not be the last time you get "angry". How dare your husband tease you like this. The guy must be a real prick. All you did was make one little mistake right?
I don't know how long you have been reading this board but it obviously wasn't long enough. Your husband is a better man than me I guess. I wouldn't have anything to do with this couple again or swinging in general for that matter, at least until the trust was regained. Not only did you fuck up...so did the other husband. I wouldn't trust either one of you right now, especially together.
