yeah, you screwed up... sorry for telling it like that, but driving one hour every time to see her with flowers and stuff... from my point of view, you took it all too seriously, lost your head and scared her... it's nothing uncommon I would say, happened to me too when I met awesome girl never having gf before... I don't really have any great solutions, you should do as your friend says and stop messaging/calling her, there's no point, if she's not responding... of course, she can have her own reasons, there are countless possibilities but that changes nothing on a fact that you should stop thinking about her so much and take it easy... if she calls you, good, if not, well, time to move on... I'm sorry for that:(
