Try

Our relationship is always hot and cold
Never a somber in between
You're always shining through
Or getting lost in the crowd
I know you know what I mean

I think I know what's not working here
You're to selfish to let anyone love you
You're to spineless to let anyone in
The funny part is I thought we were the same
The funny thing is I thought we connected

And now we are just running in circles
We are chasing ourselves like never before
Out of breath with nothing to show
You were out of line, I was out of patience
All we've got now is a botched experiment

Once we were both in it for the better
Now we are just in it to survive
How exactly would a divorce go between us?
Is it even possible by this date and time?
Neither of us are getting out alive

But then there are those moments
Those few seconds of bliss
It makes even the most hardened cry
That is when you realize why you're still here
Now I remember why we still try
