Chandler Riggs...

You and Chandler are dating, you knew that he had another girl before you, but he "ended" her for you. One night, Chandler begged you to both go to a party because his friends invited him, you accepted reluctantly. At the party, Chandler told you that he was going to the bathroom, you nodded and continued talking normally with his friends. Chandler had been late for a long time, so you decided to go into the bathroom and found him kissing that same girl, that is, his ex. Chandler, noticing your presence, quickly went to you and took your hands and tried to explain but you gently pushed him away.
-You lied to me, to go back with that other woman! You said, as you looked at him with teary eyes.
-Don't you understand? You are the other woman! He he said seriously as he looked you directly in the eyes.
