Reality check

I see you with Claire
And all I can do is glare
I see you with Jane
And all i can do is ache
I see you with her
And to pieces I shutter

It hurts seeing you with her
It hurts when you give it to her
My favourite kiss of you
When your lips touch her forehead,
A million pieces my heart breaks
But what hurts more,
Is that I settled for so less

I knew what I signed up for
When I showed up at your steps
I knew what i signed up for
When I opened that tiny window
For you to have a glimpse
Inside my haven
