<human>: I have a weird dating issue. 
(Using an older cousin's reddit instead if my own, btw)
There's this girl. (I'm a guy). 
I'm a "Mormon." She's a Mormon. I'm 15. She's 15, but a bit older. I don't really believe in the church and I don't know about her. We're really into each other. I'm trying really hard not to go to fast.
We don't see each other so when she invited me to a beach trip I went. We held hands and nearly kissed but the adult leaders were irritating. I invited her over to a friend's house because my parents are really Mormon. We're having a double date. 

She texted me earlier that he loved me. 

She doesn't have her own phone so she borrowed my friend's to text me. I don't know how to manage this. I've been with a few people before but I really like her. I'll see her the night of the double date. We're watching a horror movie. 

WHAT DO I DO?!?!

Can you give me a shortened version of the text?
<bot>: My S/O said she loved me really fast and I don't know how to respond. I really like her but I'm 15 and won't do the sexing with her. What to I do?
