what you gonna do if you saw your gf has backburner guys?

I saw my gf’s IG talking to her past hookup. but no hard flirting yet just kamustahan nagreply lang yung guy sa story niya, and this guy may bf nag aaya sa place nya and all. then I don’t know if this reply is just playing cool, eto yung reply ng gf ko “haha baliww!!”
