She might need to get her travels and exploring out of her system and could very well decide that none of that matters anymore and you want to be with the person who makes you happy. Happened to one of my best friends. She went and saw the world and decided the right place for her was a rural Minnesota farm town, population 480 and was lucky enough to rekindle things with her ex and they are now happily married.
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?
