Am I over thinking this?

Over a year ago I matched with a girl in a dating app. We've talked and I asked her out 3 times but she basically declined, then she decided she just wanted to be friends. We both became single again and she asked me out to hangout (that's what she called it). We ate, laughed, locked eyes, she even touched my arm a few times and then later we went rollerblading when I was taking a break she kept roller blading and smiled at me really hard. On my way to drop her off he liked my music and complimented my voice and wanted to sing with me so we did. Is she gaining interest in me? She 110% knows I have interest in her. We didn't hug, hold hands, or kissed at the end of "hanging out".
Am I over thinking this?
