er... thats how relationships go. there is an ebb and flow.
if you have regained a love for him that he currently doesn't return, you need to give him (and yourself) some space. he is his own person. if he is depressed or whatever, let him be. just be there for him and try not to impose yourself.
it might never become the full-on relationship that you (or he?) want, but at least you can say you've done all you can.

You're only 15, it's unlikely that you really know what "real love"...as corny as that sounds...is, you're probably just running on infatuation, especially if your feelings keep changing.
My advice: back off, cool down, and wait to grow up a little more.
i'm still unsure how he hurt you.
his feelings changed and he dated someone else. so?
