What is her family like, have you met them? What are her friends like? Is she hanging out a lot with the friends from the bar? What is she doing to earn money now, did she settle down and get an eduation? Does she share this past with you with "I loved doing all this and found I constantly enjoyed it"? Did she experiment a lot with drugs?

The OP is only 22, that's very young yet. She is two years older and girls tend to mature faster than guys to begin with.
