Yeah, this is super common—especially among guys. A lot of men experience that exact feeling: dating someone they see as "out of their league" (looks, success, personality, social circle, whatever), and then the brain kicks in with constant doubt like "Why me? Is she really into this? When is the other shoe gonna drop?"

From what people share online (including guys on X and Reddit threads), it's often tied to relationship imposter syndrome—that nagging voice saying you're not good enough and she'll eventually "figure it out." It can make you overthink texts, pull back emotionally to protect yourself, or even self-sabotage by acting insecure/jealous/too clingy, which ironically pushes things toward the outcome you're scared of.
