I want to tell her how i feel?

Don't tell it to her over text. I think going over to her house is the best idea because you don't know if she will show up to the movies. Tell it to her straight. Tell her you like her as more than a friend. I wouldnt say love though. Thats going a bit too far. Tell her in a way where she isn't obligated to date you but where she has an option. Just speak your heart out. Lead up to it though. You don't wanna just drop it on her.
