When you know in your heart that it's meant to be , even when your mind says no and your heart says dive in with both feet and and also when your gut says so too. That's when you know when your deeply in love with somebody ;)
I think you know when your deeply in love with somebody is when you care alot about them and you would do anything for them. to know if your deeply in love is when you want to be with them even as you progress more in life. Love is a big thing to have for that speacial somebody, but if you love them deeply, then you will know that you will want them in your life and not have to let them go.
when you care deeply about somebody

Just be there for that person and be a friend and your time will come
Simplest way is to ask them.
No one knows
then you're a terrible person.
Nobody never knows why they love so deeply. This is a 12 year old child telling you that love can make you crazy or you can just be continuing to be normal. Love makes me shy and bad. I don't know how love make you though. So that's my opinion.
It means they are deeply in love with you.
Love always and deeply love forever till death and deeply as in so meaningful that nothing can break it.
Ask her!
When the one you love, already loves somebody else.
it depends if u believe in love in first sight u know when u r in love if u can stare in their eyes deeply and c somethin special in them
