i went throught the same thing. my ex didn't call me for my birthday and it killed me. after waiting a few weeks, i called and gave him a piece of my mind. to be honest, i would've gotten a better response talking to a wall. it's their way of saying "we're not together anymore so i don't NEED to call you". it sucks and i know it hurts. trust me, don't waste anymore energy on her. ------------------
