You are better and you need to work on moving further in that direction.
Surrender. It's a liberating word. It means you stop resisting.
It is not your W you are resisting, or her new R. It is your own emotions and place in life that you are resisting. That is making you stuck.
As nine said, your ritual of touching "her side" of the bed is just one example of many that keeps you stuck. Stop resisting the reality you find yourself in.
You have a full bed. It might be time to sleep in the centre of the bed, or even move to "her side". It might be emotionally uncomfortable at first and possibly even physically uncomfortable. What you will find when you put yourself in that situation, you will find that things start to change positively. You will look at certain things that have kept you stuck in a different way, and then you can act accordingly. Affecting your life positively.
We often hear or remind ourselves to believe none of what we hear and 50% of what we see. That we need to remember that they are hurting, too. And maybe... just maybe... for the next week, may I suggest you believe everything of what you hear and see. Allow and surrender to the idea that she IS happy, that she HAS moved on, that she IS NOT coming back.
Give that a chance for just one week, and see how that's helped your detachment.
