Falling with no reason

Can I find a reason
For the fear in my heart
Might it be the idea
The idea of love
Or could it be how fast
I'm falling
Falling hard
Into something so new
But it doesn't feel too quick
Or wrong in any way
But just as if it was meant to be
From the very first day
His heart is always
Ready to love and to forgive
I can't believe I'm lucky
Lucky enough for him
But even more I can''t believe
He loves me in return
