[疑難求助] Need help...girlfriend chat with guy closely

KENNY8

Recently my girlfriend did texting with a guy that she just met very frequently even like reporting n telling him where she Is n what she do almost everyday. N they did talk through phone almost everyday while I am not beside her. Although the content Is like normal chatting in message but Is it anything wrong? Why need to report everything to a guy n yet he Is not her boyfriend? Is it correct that girl can chat n text with a guy in that way? Should I let her know n ask her Why she did that? If yes how should I ask her about this issue? Please advice n help me. I am really struggle in this issue badly. Thanks.
