Sounds like it got back to your wife from the OM and then from your wife to the sister......
This is good....
Funny though that her sister told you it was between you and your wife and now she is butting in. I wonder if she told her sister that it was between you and your wife too?
Obviously this has effected the relationship between your wife and the OM or there would be no reason for you to back off would there? If it was going so well your wife and the OM should now be happy because they can now have each other ..
Telling you to back off means that things are no so great in loverville. The OM must be backing off from your wife and she is confiding in her sister that it is your fault... Hang tough.
Sounds like things are proceeding just perfectly the way it should here.
