I asked him not to go...he agreed to that. He told her he didn't want to go. She persisted. She went behind my back asking him to another "sex party" he assumed it was a SM party.
I don't interrupt their dates. Of course that is 100 percent fair. What she means is that she doesn't want me to ask him not to go to sex party because she feels that is controlling her time. However, it is something I requested and he agreed to.
