Love is blind

The famous saying states that "love is blind". So if your girlfriend catches you cheating, she didn't love in the first place because she should have been from the fact that she loves you. In other words, if she loved you, she shouldn't have seen you cheat.

Person 1: "Bro my girl dumped me after catching me with Lisa"
Person 2: "Damn really? You know what, she didn't love you because love is blind."
