Explain to us how your wife and the married OW are contacting each other.
I still think your story and explanations sound a bit suspect. You are actually blaming the OW as if it was ALL her that was doing the pursuing. I don't buy that one bit. No sex? I don't buy that either. How can you expect your wife to buy that?
The reason this stopped is because you got CAUGHT and your wife did what people on THIS site should do when their spouse is in an affair... TELL them they need time to think and tell them to leave. Wakes you up FAST doesn't it?
I think you are concocting this story on here and leaving out YOUR big part in this phone sex, best friendship and a host of other things so that we will help you to get your wife back. I think you need to come totally clean here first. I don't know how your wife will buy this stuff if an unknown stranger like me doesn't buy it.
