A month ago you met a guy at a bar and you quickly started dating. A couple of days ago, when he took a shower, “Mariko” started calling him. You didn’t know about this girl, when you went into their correspondence, it turned out that he cheated on this girl with you.

What should you do with this? In front of you is your phone, in which Mariko’s contact is open, should you write to her that she has been deceived by her boyfriend?
