Found out my then girlfriend was getting around (3 other guys, ya, that one stung a bit..)
What an uncaring inconsiderate {bleep} to do that to you. You're lucky to be rid of her. It's best to forget that she even existed. No need to waste brain energy thinking about her when there are millions of girls out there more caring and trustworthy.
As for money, I have had many highs and lows in my life and I've discovered you can actually be equally happy with and without money. It's strange, but I've gotten more enjoyment eating peanut-butter toast after a day of starving than I did eating a $100 meal at a fancy restarurant. I've had luxury cars that were nothing but trouble, then discovered that having no car at all was a relief. (unfortunately, the same theory doesn't work when you can't afford an Amiga accelerator... ;-))
