Based on what you've said, I get the impression she isn't interested in you any more. You seem to be the one doing all the pursuing. You messed it up and it looks like it's over. Despite me saying you messed up, you did apologise, you bought her a gift and you've made an effort to patch things over. You've done all you can do and if she does dump you over this ( being rude when drunk, being a bit aloof), then I think there's more going on with her because it seems like an excuse.
