As Chris Brown sits alone in a jail cell, friends of Karrueche Tran are speaking about the couples' breakup and spilling the deets about what FINALLY made her leave him.  Surprisingly, it had nothing to do with Rihanna's alleged secret trip to visit him in rehab.

Sources told TMZ that Karrueche visited Chris last month and saw some inappropriate texts from other girls on his phone. That was her breaking point.
