Talk is cheap but people can mature. Make him prove it by actions...calling when he says he'll call, keeping plans, wanting to take you on real dates, spending time with you getting to know your mind, not just your boobs and vag. Don't put out in the meantime until you know he's legit.
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?
