Do you ever feel like he’s eager to show you off to everyone? It’s like he’s saying: World, look at this woman! She’s all mine!
Well, that’s an obvious sign of how much you mean to him. He’s more than proud to kiss you and hold your hand in public so everyone sees you two as a couple.
Besides, he has absolutely nothing to hide since you’re clearly the only woman he’s dating. You’re his babe.
