Female here.

Yeah..you screwed up somewhere between the meeting up with her at the show, and her finding out you drove an hour for her.
If she's sarcastic, she's probably a bit cynical, and not really the romantic type. Instead of seeing your one hour trip for her as a charming act, she found it creepy and perhaps a little bit desperate? It certainly didn't help that you left her numerous voicemails despite getting no reply. Finally the fact that the friend actively intervened and told you to back off was the last nail on the coffin.

I think you started off well with the flower (not rose), but quickly came undone. You can't show that much commitment to a girl when you first meet her (driving one hour for her). It would creep any girl out. Even if you feel compelled to, it has to look casual, spontaneous, and effortless to her.
