SoulMate Question

I'm telling him now. I've said 'I love you' to him beofre but I'm telling him again

"Its not just hormones. He's been their for me through everything. I don tknow its hard to explain"

I simply must point out that you're 13. You haven't finished puberty (you've barely begun it, in fact) and so you don't actually know what "its not just hormones" even feels like.

What you described isn't even love - it's infatuation, which is both extremely common and hormone-driven. Calm down and go about your life. If he's really your soulmate then there's no remotely reasonable thing which you or he could do to ruin it. If you are meant to be together then that is how you shall be, so why fret and freak out?
