A word i couldn't define

I never knew what love was, until the day I broke up with you
And I never knew what we had, was love so pure and true
I blew it with you cause love was a word I couldn't define
And what scares me most, is not knowing if you can ever again be mine
Because I now know that love was what I felt
And still when i see you, my heart begins to melt
All I want is to feel that love we had again
I want to make now fell like it did back then
