I NEED some serious help here. Im confused like no other.?

This girl and I met at work and recently went on a date after I was told she thought I was cute. I took her out to dinner and then we walked down on the waterfront. We held hands and cuddled on a bench. It was about 9 when she said let's head home. I walked her to her front door and she gave me a kiss before we left. I texted her later telling her that I had a great time and told her how beautiful I thought she was. She responded by saying "your a sweetheart I had a blast with you". The thing that threw me off was the sweetheart ( considering were both 19) and the fact that only after 3 hours of hangning she asked me to drive her home. Can't tell if she was being nice or if she likes me.
