What Should I Do?(A one direction/ R5 fan fiction) {EDITING}

Hi my name is Dillon I am 18 and I have a two year old son named Kyle with Niall Horan of One Direction and he doesn't know. Should I tell him?Or should I just keep it a secret like I have been for three years?(P.S me and Niall aren't dating)(PLUS: In order to keep Niall from knowing and to keep Kyle's Irish heritage strong I moved to Dublin)
