Beware when they quit fighting....
It means they have stopped caring.

So, so true. You can never hate something without loving it first...
....and not caring is the withdrawal of all emotional attachment from your ex love.

On the upside, however - it does free you from withdrawal symptoms.
It give you a newfound enthusiasm and energy to be applied elsewhere...

...plus the totally infantile satisfaction of showing your ex-lover, just how well you are doing without them, and that you were right, all along when you finished the relationship saying ...

"....look you twat - it's fucking, you ok? It's not me..." lol...
