Ah. i see. I can totally understand that. My GF and i had that issue for a while... Well, it was more like she wanted me to tell her things, but i didn't because i didn't think she'd want to hear it... But in the end it kept biting me in the ass... But once i got over myself, and started sharin things with her it got better. Lolz. ^^
But, in the end (Unfortunately) it's more about you than it is her... And if the relationship is really doing nothing for you, then there may not be alot that you can do, and (Also unfortunately), sometimes you just have to know when to cut it off and run...
