Unfortunately, the only way to feel that way is to actually believe it.
You can't make her want to go.. I would begin the process of finding someone else who might want to go. This will do several things:
1. Keep your mind off of her where it should be. 2. Boost you PMA 3. Prepare you for the worst 4. Show her that you are serious about moving on
As for the ring.. that is a personal decision for you to make. I took mine off. I'm prepared to move on. It's just where I am. By wearing the ring, you are telling others you are still married and not available.
Is that how you feel?
If so, then keep it on.
If not.. take it off.
Mine is, ironically, in the set of wine goblets that her father gave us for our wedding.
