NOW, WOULD I B WRONG 4 TLKING TO ANOTHER GUY?!?! I MEAN I DONT THINK IT WOULD B WRONG B/C MY BOYFRIEND IS MESSING UP & MAKING ME UNHAPPY... PLUS I THINK THAT HE'S CHEATING ON ME!!!...I MAY SOUND LIK REALLY SELFISH BUT HE IIS A BIG FLIRT!! & HE DOES THINGS LIK TXT IN MY EAR ALL NIGHT LONG AND DONT ANSWER MY CALLS AND TELLS ME THAT HE WAS SLEEP THE NEXT MORNING OR SOMETHING LIKE THAT..!!
