Is there any way you can talk to your parents (or hers) and try to set up dinner or studying at one of your homes? If its a trust issue maybe they will start to give you some alone time, as in letting you watch movies in the livingroom when they're home but not in the room with you two.
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?
