Girl troubles, really confused?

Ok so I met this girl on Friday thAt was coming to visit one of my other friends, and we went out for a walk. Everytimei would slow down and get behind them, my friend (also a girl) would ask me to get in Front of them and whenever I would, they would start whispering to the point where I new that they were tLking, but didn't have a clue About what the new girl was whispering about. So later on when We all got back to the house, my friend's little sister started to listen to what they were sayiny....and all of the sudden the little sister yelled out "YOU LIKE HIM?!? While pointing at me. So I played it off as nothing. So on saturday when I saw them again we were allriding in the back of m dads truck and snce I was cold she snuggled up to me. And also whenever I'm around them, some of the girls make little side jokes about her liking me, and me liking her. I thinkthat she is awesome and I'm almost completely in love with her, because just About every other thought is abot her or an image of her. So all I want to know is: Do you think we are rushing it and should slow things down, or do you think that everything that's happening Is normal. Ps: We're both 14 although she's several months older than me(im in November and she's in february) andI live in the us and she lves in south Africa. (we're both white if that makes any difference although I don't think that it does). She's also goig to be staying until the 30 of December(ts December the 6th today). I love her and I think that she love me but I can't tell. Thanks for all of your help in advance =D
