Two faced

I thought i knew her inside out But now im having doubts Was she just playing a game Making me feel insane Im not saying she cant have friends But this sudden change is hard to comprehend How can someone switch sides so easily Is this just a phase or is she really this sleazy I dont know what to believe anymore My ex's have left me sore I'll just keep my distance and move on I don't need someone two-faced in my life to go on
