Im in love with him already??

At thirteen, "love" is a hugely impossible word to use. I know infatuation (a huge crush) feels like love because it is SO intense, all-encomping and pionate, bit it is ALSO temporary. At your age, your hormones are having a field day and you're coming into an age of fertility, so you're naturally realizing the attractiveness of men in a way that is different from when you were younger. The intensity will fade, I promise. Real love is an unconditional decision made every day you wake up: a decision to forgive, support and adore. It is real, sometimes it is difficult, and it is years and years ahead of you. For now, you may just need to feel heartbroken. At 17, this boy has an emotional capacity far beyond yours, and a maturity you haven't reached yet. It's like a little girl having a crush on her daddy, practically. So for now? Accept that he has a relationship, respect his relationship, and stand back and admire the view. Realistically, you'll never get any more than that with this one. Better luck next time.... and in four years.
