Theories:

1. Matt Damon is secretly a commitment-phobe, hiding behind a façade of charming, Oscar-winning smiles. His love life is a carefully crafted illusion, designed to distract from his true nature: that of a lone wolf, always ready to pack up and leave at a moment's notice.

2. Matt Damon is allergic to love. Yes, you read that right. His skin breaks out in hives whenever he gets too close to a serious relationship. It's a real thing, we swear!

3. Matt Damon is waiting for the perfect script. He's holding out for a role that perfectly captures the essence of his heart: a lovable, yet emotionally unavailable, leading man with a penchant for adventure and a fear of commitment.
