It may be rebound but that doesn't mean he's coming back to you. He's got his weiner in someone else, he's not thinking about you. Sorry. Sounds like it was a rotten relationship, the trust and your admitted nagging. Learn from your mistakes and start fresh.
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?
