After an untold number of failed relationships, the best I can tell ya is that I don't have a clue.
BUT...
I finally scored a failed relationship that wasn't my fault.
So I feel like I'm finally ahead of the game.
I'm used to giving away half of my stuff all the time, too. Works out good. I don't have near as much stuff to clean.
I hope to get married soon so I can get rid of some more of this stuff.
