Girls, do you think she likes me?

A friend and I went down and visited a girl that I have been talking to. We live an hour away from each other, and she has been down to visit me and has gone bowling with me. She is usually commenting/liking my Facebook status updates. Well last night she was really giggly. Laughing at most of the stuff I would say, and she laughed at some of the stuff my friend would say. You could tell a difference between her laughing at the stuff I said compared to the laughing at the stuff my friend said. I noticed she was looking at me and twirling her hair frequently. When we were riding around with her, she and I fought about the radio station causing she and I to have a hand fight we grabbed each others hands pulling it away from the radio. She runs a snow cone stand and the other day when I went by to get one, she wouldn't let me pay. Last night I gave her some money and she threw it back in my truck. She ran inside her house before I could give it back to her and she stood by the window laughing. I think she likes me, but I want some others opinions. I asked my friend, but he was no help.
