Confused

You puzzle me
One day you are clingy, as close as can be
The next you are farther away
Like it's just another day

I wish to understand
I love you, but the feeling isn't mutual
Why then do you do these things
That make it seem possible?

You confuse me
It's all hugs, sweet and carefree
Then almost no talk at all
Sometimes you make my heart fall

I just don't comprehend
Can you please explain it to me?
How much do you like me?
Why are you my boyfriend?

I love you
You know it's true
But I just don't get it
Am I unfit?

You puzzle me to no end
Maybe that's part of the experience
But I wish to know, I wish to understand
Please...explain my boyfriend...
