Something went wrong and i need your suggestion on what to do?

Sounds like you should just let it be for a while. If it's meant to be, then it will be. Talking to her parents too early might be a bit pushy. You need to relax and let her parents mellow out, then go talk to them as an adult and explain the situation. During this time, continue to smile at her but don't limit yourself to just her if someone else comes along.
