Staticsnake, given the amount of threads you've started where you're questioning your and/or her behaviour, it's still too early to be thinking 'forever'. Thing is, all this questioning means that you don't trust yourself to read her properly. Also, I suspect you don't trust that she feels the same way about you.
When you can be confident of your and her actions, then you'll be ready to start thinking about the future.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
