Girl's Behavior

If someone rejected you 5 years ago comes back and says they're so sorry for treating you badly? What would you do?

So 5 years ago when I was in High school entering college there was this one girl I really liked. I was inexperienced and shy. So, we were not that close of friends but she did like me as we would hangout sometimes but after a couple of months I asked her out and she rejected me. Saying something on the lines of, "I don't view you that way. I have someone else. Sorry!" I was a bit hurt but obviously it doesn't bother me anymore. When she rejected me she said that she was sorry for leading me on and then started leading me on again and rejected me again. She'd try to make me jealous by flirting to other dudes and I had enough so I just ignored her. Anyway, after university I've had more experience and am more confident. Last week I met her in a store and she said that it was a surprise meeting me after all these years. We exchanged numbers there. After that she stated how 'Sorry she treated me that way and that she was immature and shouldn't have done anything like that. I joked around a bit saying that she was immature and we laughed it out. So I don't really know? Should I take a chance. Can someone go from bitch to mature in 5 years?
