Just type her a message, by the time she translates it you'll have it all figured out.
I've been in this situation once and it didn't end very well. It was new years too. She was way too into the bar scene, every night. I tried to hang on but she was sleeping around. I was a fool. If you can control those emotions being friends might be a good way to test the waters. You'll be able to find out if she has really changed or not. Just don't lead her on and don't sleep with her, yet. Also don't go out of your way for her, we don't want her to be the puppet master. You should be able to tell within a few weeks if you guys still click. You'll also know if she was sincere about making a mistake and the bar life wasn't really for her. This would be the approach I would take, carefully.
If you can't control those emotions, then you need to decide if you want to take the chance of getting burned or not. Then you need to decide from there. If you decide it's really over then tell her that you can't see her anymore. Just be nice then in a short time you'll be friends since you didn't burn the bridge.
