Do you think he's interested in me? (read description)?

You cannot be saying there is no guys in your entire school that you could not meet and get to like! Picking a guy from another school means you will have a text and FB relationship with maybe a meeting once in a while. If you want to settle for that, go for it, but you are cheating each other from the chance to meet someone they can send time with daily. Keep in mind about your age. This is not the guy you will end up marrying, so why choose to have a long distance relationship with a guy you really hardly even know? Be nice, keep in touch with him if you want, but let him know you two should give each other the gift of caring by being friends and letting each other find a partner at each of your schools. Do the right thing, the mature thing, and in the end the best thing for both of you. Good luck!
