Do I or not?

There is me(14)there is 1 boy at my school called james(15). He used 2 b really popular but now his friends have worn off and he only has a few. He used 2 talk to me all the time but just walks past without saying nothing now. Some people say he is smelly(which he isn’t) he uses like 1 can of lynx a day! Then this morning not knowing I was talking to one of his old mates on the phone he came up to me and asked me if I’d go out with him. I really dint know what to say because me and his mate was still on the phone. His old friend started to laugh and came running to me still laughing while james was stood there!! I used to really like him but then I got totally over him and now I’m starting to like him again but his friend says I shouldn’t because he’ll just dump me when he gets bored but he has never had a girlfriend.
