Questions: Girl's Behavior

I've been talking to a woman I met through work for a year, but increasingly since Christmas. We went 2 weeks of not talking when we had a disagreement after I asked to meet her a few months back and she said no. But after 2 weeks she reached out to me and we stated talking again. She has a strong history of cutting ties with people if they upset her, so I felt special when she reached out

I've liked this woman instantly since the first time we spoke on the phone. I'm sure there was attraction from her in the early days, but I was too afraid of making a move, so we became friends. I really like her on a personal level, she's amazing. I think I've said enough for her to know I like her without me directly telling her. My god, now I've met her, I think she's the most stunningly beautiful woman I've ever seen

We talk a few times a week, and our calls are at least hour. We are very supportive and caring of each other

Todays her birthday, and I am in her town for other reasons. Last night I told her I had a present for her and if she wanted, I could take it to her, but told her saying no was ok. She told me to take it this morning. This is the first time we've met in person. She's also moving house today so was packing her car when I arrived and she asked me to help. The conversation wasn't flowing as it usually does, it was awkward. She didn't really make any eye contact either. As we were loading the car, she asked if I had to go. I said no, but then she asked again once the car was loaded. She said she was cold and stood with her arms folded and looking into the distance, so I took this to mean she wanted me to go. I said good luck. She said thanks for the gift, and that she'd catch me later. For this she did look me in the eye. She was always smiling but I'm not sure if it was real

I'm feeling deflated now. I had butterflies, and was hoping sparks would fly

What do you think was going through her head. Does she reservedly like me, or was there no interest at all
