Speechless would be a good start,
Together could be a great ending and
Love could be an great explanation.

I had a hole filled with nothing in my heart before I met you, I expected you to fall into it and look for a way out without a farewell.
Instead you toured it, you discovered every flaw, insecurity, broken dream and lost prosperity and you filled it up with everything you had.
Tonight my heart feels complete and normally my mind would be empty but, it's lost in the valley of what could've been and what is and what I want.
And right now my love,
You are definitely a need.
