Bird of a feather and apple never falls far from the tree and that jazz. Maybe she won't cheat but its not looking in your favor.
When did you find out she'd cheated on her last man? Did she seem at all remorseful? That would be the hugest of red flags to me.
So, so you think you can tell Heaven from Hell,
blue skies from pain.
Can you tell a green field from a cold steel rail?
A smile from a veil?
Do you think you can tell?
And did they get you to trade your heroes for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
And did you exchange a walk on part in the war for a lead role in a cage?
