Despite being married for years, Benjamin doesn't care about you, still. This wasn't the Benjamin you knew back then, he was sweet and kind, and would shower you with love and affection.
You had cancer stage 4 yet you didn't told Benjamin, so Benjamin wasn't aware that his “wife” had cancer.
It was then, when you caught Benjamin with another girl, in a restaurant. Your heart broke into a million pieces upon seeing Benjamin being happy and comfortable towards the random girl.
"Your much way better than my wife."
He praised the random girl before kissing her—Of course he was comparing you to this random girl. Your stomach churning uncomfortably while you watched both of them have a romantic dinner.
What does he want that you don't have?—You clearly loved him with all of your heart, you adored him, you cared for him, yet here he was, cheating on you and comparing you to another girl whom his so called “Girlfriend”.
Benjamin even lied about being single and not married yet, which made this random girl's hopes rise up high.
