Well you guys have only been together 2 months, you aren't obligated to have to tell her everything right away. It would be one thing if you'd murdered someone but you hooked up and it doesn't sound like you are a manwhore, if she can't get past it maybe you are with the wrong girl.
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?
