Can you prove the she was talking to OM when the call came through? Or was this just her word? I am thinking that if you have 2 phones, you can dial on one phone and the other person answers and will have to end the call with you to answer the other call.
Also, I am sooo sorry to tell you this, but one if the #1 reasons that someone wants "space" is to keep a relationship with someone else going on.
At least the OM is threatened...and good job getting the police involved with his pathetic threat. I guess being threatened means he senses that your W still loves you.
I think the vets here will give you some good advice on how to proceed next but the classic "no contact/last resort technique" might be in order.
