All I can really say is to use your best judgement. I mean it's oki to b curious and want to know what your crush looks like, but it's a little suspicious if he wouldn't just give you a picture of himself, instead of you having to go to the school website (although I don't know if he has or hasn't). And no, It's not bad, because you didn't really turn him and his brother against each other. You didn't feel the same way and that's how you feel, no shame in that luv. Lol and I don't know about your picture being in his wallet, that's a little creepy, not gonna lie.
