what happened?

"..What happened baby? What happened hunny? .. to the way things used to be ,."

Yet, I wonder. Was it me?
What on earth did I do, to cause you to act the way you do?
Instead of holding back, i sometimes choose to give you tiny parts of me,. That backfires,.
I'd express feelings. You'd rather for me to keep them to myself.
I'll tell you I love you, knowing I want to say more,
like how I'm crazy about you , & how I miss who you used to be ,
but it seems like all you can say is (iloveyoutoo), with no feeling.
I think it's my fault for expecting more to come from you.
I think it's my fault for seeing what I see in you. It's all on me.
I can't get over you, or seem to allow myself to.
I've fallen in love with the person I want you to be ,
the person I once knew you to be ,
the person I wish you were .
& everyday I face stinging disappointments from the person you've turned into.
It hurts.
I'm no mind reader.
It'd be easier for you to tell me what I don't know.
I'm tired of feeling second-best, like I'm not good enough for you.
If I painted the most beautiful picture, it would just look like crap to you.
I'm tired of the confusion, & having to force things out of you.
Everything's a guessing game when it comes to you.
I can't read you anymore.
Your book's in another language.
We no longer click , I feel like we're strangers .
Like all our memories were washed away from your brain.
& yet I couldn't leave you alone if I wanted to ,
deleting your number out of my phone didn't go far.
I couldn't stop thinking about you if I tried.
I can't get you out my head.
I love you, more than you could ever imagine.
What happened to the person I used to know?
