Was it love?

Was it love I felt?
Was it love I felt that October?
I felt as the world was finally good.
I felt as if I lost you, I would die.
Was that love?
Or was it just a misunderstanding?
All I know is I still feel the same
And don't know what to do anymore
With those feelings.

-Can someone help me? I don't know if it was "love" I felt with my exboyfriend and I'm wondering if someone could help me with that.
