It seems that her boyfriend ran afoul of some governing body of his profession. Somebody sent him an email regarding this (not sure whether it was a threat to turn him in to his current employer, or what). Regardless, the wife is blaming me for sending it. Of course, I did no such thing. I tried to tell her on the phone that I didn't do it (don't even know what she was talking about). When I saw that I was getting nowhere with this, I ended the call.
Also, she said a couple times, "You are blowing a chance here." Thought but did not say: "A chance for what???"
I followed-up with terse email stating that I will not beg, and I will not plead... but for the final time, I did not send the email. I have neither the time nor the energy to concern myself with these kinds of things. I told her I am focused on myself and my kids and she is free to do whatever she wants, I don't care.
I have no idea whether the person signed my name, or they just jumped to the conclusion that I sent it. Don't know, don't care.
