Help i accidentially rizzed but it was awkward

So i was walking with my dad and brother and ran into a girl from school. Never really had a crush on her but she is probably the best looking girl in my year. Anways she sees me first and says “Hi!!”, enthusiastically walking towards me with her mum. She puts her hand out to dap me up (i think) and then after that I went to lightly tap her left shoulder as if to walk past her (for some reason). She thought i was going for a hug so she tries to hug and and then my dumba*s only realised when she was about to walk away. So i hug her and she sort of spins around like one of those romantic movie scenes where the guy pulls the girl and she spins into his arms. And well yeah.. I think im in love
