Does she like me? Girls help please :(?!?!?!?

Okay well to start off I'm 13 and she's 15. I see her at church every Sunday. I know that your prolly gonna say I'm to young to know what love is blah blah. But I think I love her lol. When I see her everything melts away, my heart beats faster, my hands get really clammy and when I close my eyes I see her. I'm extremely shy, don't really talk to anyone. And she knows but she still talks to me a lot. I've known her for maybe 2 months. We've told each other stuff that has happened in are lives that most people don't know about. And maybe 3 weeks ago she gave me her phone number. I didn't ask for it but she said if I ever wanted to talk to her just call or text her. So I text her everyday I am right now lol. I told her she was pretty once it was on fb because I'm to shy to tell her in person. She invites me to go a lot of places with her and her friends. And she invites me to sit next to her in church. Everytime we make eye contact we both smile at each other. I'm 2 years younger than her but I look older lol. I think I may be mature enough to date her, maybe maybe not. I can't be super detailed so yeah. Oh btw I've never had a gf lol. So could she like me? Advice?
