Should I let him go?

Geez....is not like you're 80 years old...he is the best thing that has happened to you SO FAR!!!! The fact that he is telling you about other girls, and he is having girl trouble, should be your flag that tells you he is out there in college meeting other girls, and you're not the only one. I would say let it die, and wait your chance to get to college because then you will have many, many guys to choose from.

Move on sweetie,if he is the best thing that has happened to you then he might be a good friend for you,but just a friend.

Well, you wouldn't keep stuff from him if you loved him. All I mean is, you should tell him how much he means to you and what a difference he makes to your life. This will make him feel valued.

Plus, if he's telling you about the girl trouble he's having it means you're very very special to him because I don't know of many guys who open up to girls about their personal life.

But yeah, there ARE loads of guys out there and you shouldn't be centering your life on him now, especially when he's taking it easy and going around with other girls. Just talk to him, maybe he's too shy to tell you how important you are to him. Goodluck :)
