Is it normal? i just can't get over...

Hi! Is this normal? I met this girl inside the church last december, she was a member of the choir and seeing her was accidental. I know I'm bisexual since young, I tried drifting my attention into by boys but it wouldn't work. When I met her I felt my heart beat fast again,and for the next days I realized I'm falling in love. Bad thing is, I don't have the courage to talk to her and ask her name because I'm afraid of rejection (It happened to me when I was younger) I could see her looking back, but I'm not sure If it was really me or someone behind me. This January, I saw her with her friend, I was riding my bike back then, and when I saw and passed in front of her and looked back, I saw her looking at me, she was not smiling, she was just standing and staring at me. I looked back where I was heading my bike to and when I came back to that place, she was gone.
Now, I just can't get over things, I'm imagining myself with her but I'm afraid of what people will tell us since we're in the same village. please. I need advice. I just can't take it any longer.
