Not Sleeping Around

I don't know if I'm right but I'm not wrong, just now
I don't know what makes you think I'm so strong, somehow
It's in keeping with my not sleeping around
You keep thinking I'm tired of you but I'm just tired
While I keep saying you're sick of me but you're just sick
It's in keeping with your not sleeping around
You only do it 'cos you can, you only say it 'cos you can
I'm supposed to take it like a man, what if I can?
I can't give more, you can't take more
I can't keep it from my head that you're never around
You're never around, you can't get yourself out of bed
So, you never come round, you never come round
It gets too hard for me to think, that becomes too much to drink
And now, I'm scared that if I blink you'll be on the brink
Of needing a free roam, please don't let go
