How do you deal with loosing a soulmate FOREVER when I mistakenly pushed her away? Now she's happily married.

Criminies! Cry me a river. One way to get over it is to start thinking of her in a more "best wishes" positive manner and to go out and re-discover the world on your own. Think how happy she will be for you, only it shouldn't really matter, since you will have "moved on".
