Poodles, the answer to your situation is so simple. Walk away from that JW man and the religion.
I'd advise going to the elders only if your relationship with this man were salvageable. In other words, scare him in to going straight. But it is obvious from your description of the man that he is a manipulative user who won't even confess any love for you.
You need him like a hole in the head.
Now, why go to an elder if you are going to keep the man's name confidential? All an elder will try to do is get you on the conversion track or try and find a way to keep embarrassment from falling on the organization. You will not get comfort, validation, or respect from talking to an elder.
