Told her my feelings and she doesn't respond?

Okay, me and this girl have been on a few dates lately and I love everything about her! Her personality and she's beautiful! We went to high school together and I found her in college we've been talking for a while now and gone on 3 dates. I'm kinda the shy guy that doesn't move very fast I haven't kissed her yet haha. But she asked me out the other day to go on a date with her, I said sure I would like that! Then that night after texting almost all day I told her she had a very beautiful heart and that she's the most amazing person I know, then she never responded but it was getting late that night so the next day I texted her "Hey!" Like around noon and she texted back and said I was very sweet and thanks for those kind words and I said it's just how I feel about you. Then she didn't text me back after that either.. But we have our date tonight and I'm a gentlemen so of course I'm going to find any way to pay for it, but maybe I told her my feelings to soon? I'm more of an affectionate and touchy guy and I feel I'm putting in more than I'm receiving. I really like this girl and I could see a future with her in just kinda confused because she says she loves spending time with me and stuff be she doesn't ever tell me her feelings or anything. Thanks for your help!
