If she dropped OM so fast, it just means that it meant nothing to begin with. No matter how horrible things were b/w the 2 of you lately....there is still the pull to each other...because there is a connection MUCH deeper than we realize.
Your C is right...the connection is still there...missing each other. Nurture it, slowly, it will come back to a solid flame. Give it gentle air and kindling. Not too much to smother it, just enough to feed it.
Sounds like you and W are growing on your own, and will come back together stronger as a unit. That's the BEST way to do it...the ONLY way. You can only find happiness in yourself and a person to share it with.
