I like her and does she like me?

I'm 13 and so is she and I've liked her for about 3 years now and a week ago I told her I liked her and I have feelings for her and I thought she also did have feelings for me. We play minecraft often and talk to each other on that and we enjoy it and she's been acting differently after I told her and earlier before it. She has started to help me more often and laughs at my small jokes when others don't. Started to use my type of texting language like Hai or <3 and Alright. She didn't before but now she does use my type of texting language. Do you guys think she may like me?
