My bf and I lost two good friends because of this.

It really turned out that she was upset that I wasn't yet okay with him being with her also, but at the same time she was completely unwilling to talk to me about poly and what her expectations were or what mine should be (she's the experienced poly one, not bf and I). I believe she did this unconsciously, but regardless the damage done to our friendship with her is quite extensive.
If you end up doing this and it all blows up in your face (and there's a good chance it will) you will be looked upon by the other parties with great suspicion from then on.
