Crush on Girl at Church, Does she like me?

Hi, there is this girl at my church that I have known for a couple of years, not really close, but she is in my youth group and we go camping together with the church. She recently chose me to be in a play with her. Everyone at the church said that we had such good chemistry together. I've been shy to girls in the past, but recently I've been socializing with them more often (including her). She looks at me during service. She also follows me and gets giddy when I'm near her. Am I overanalyzing this or could she have a crush on me too?
