What does it mean when a girl sends you the red love heart emoji in text?

Anonymous
I have been friends with this girl for 2 years, anyway lately we have become very close to each other. Her texting style has changed towards me like now she puts x's at the end of her text, she blows me kisses in the text and sends me red love hearts. The other day her only repsonse was a single red love heart in text. We have spent time together one on one. I feel like I'm her boyfriend but we're not dating. She says she is very lucky to have someone like me a friend constantly. We have been out to dinner, movies etc. She randomly put her hand on my leg twice in one night and she always texts me back the next morning thanking me for last night's outing.
