Based on the persona you've described, he might be somewhat guarded, especially when it comes to his feelings for his crush. His rudeness and confrontational nature might mask any vulnerability he feels. However, his confident and assertive traits suggest that he’s not afraid to express himself—though he might do so in a sarcastic or mean way.
The amount of staring could indicate strong interest, but his personality might make him hesitant to openly acknowledge or act on those feelings. He could use sarcasm or rudeness as a defense mechanism to protect himself from potential rejection or vulnerability, leading to a complex mix of guardedness and attraction.
In summary, while he might be drawn to his crush and unable to look away, his personality traits suggest he'd likely keep his feelings under wraps, dealing with them in a more subtle, possibly confrontational manner rather than openly or affectionately.
