Untitled - Ideas are welcome

I keep thinking.
How much I miss you,
How much I loved talking to you,
How good you looked
And how I loved you smile,

I can still picture your face,
And the way it looked at her,
And then back to me,
How you left her heart in pieces,
And then moved onto me.

So I'm stuck, sitting and wondering,
Were you worth it?
Are you worth it?
Or are you really the worst thing that happened to me?
