I like this girl, but i dont know if she likes me more than just A FRIEND.. HELPP!!?

i reallly like this girl but i dont know if she likes me more than just a friend, we talk alot, but her friends- whenever i go around them tease me about her, but in more of a joke way, saying stuff like: 'hey jake hows becky?' (becky is the name of the girl i like) and then they subtly laugh to themselves. we havent exchanged numbers, but sometimes, when it is just me and her and nobody else is around, she acts more 'involved' andseems as if she does like me, but in front of other people she doesnt act this way and if i come to sit with her and her friends, sometimes she herself may even make a joke about 'us 2'.. i just really wanna know if she likes me or not (ps im sorry this is sooo long lol) plss help
