However, she has chosen to forgive him, and continue her relationship with the NBA star.
But that hasn't stopped fans from raging at him whenever he shows Khloe affection on social media. After she posted a sexy snap on Instagram, fans attacked Tristan for commenting heart and love-heart eye emojis.
Many were posting the rolling eye emoji as a reply, while others used Ariana Grande's famous new song "thank u, next" to urge Khloe to move on.
However Khloe wasn't having it. She instead replied to Tristan's comments with her own love heart emojis.
Khloe has had a bumpy relationship with Tristan, but they have continued to work through their problems, and for that, her fans should respect her decision.
