Never going back
After she finally saw her ex-boyfriend for the jerk he was and that he had cheated on her, Corinna found the strength to move forward. Thankfully, with help from friends, she managed to get over Dom and left him in the past where he belonged.
In fact, they were even happier when Corinna noted that she would never go back to Dom. She would never take him back, and though she may forgive him later on for cheating, she would never forget what he did.
