Love is not what you see in the movies. Its not the ecstasy its not what you see in that scene.True love is sacrifice. Love is thinking about others before you think about yourself, love is selfless not selfish.
When faced with two choices, simply toss a coin. It works not because it settles the question for you, but because in that brief moment when the coin is in the air, you suddenly know what you are hoping for.
You may not be her first, her last, or her only. she loved before she may love again. But if she loves you now, what else matters? She's not perfect - you aren't either, and the two of you may never be perfect together but if she can make you laugh, cause you to think twice, and admit to being human and making mistakes, hold onto her and give her the most you can. She may not be thinking about you every second of the day, but she will give you a part of her that she knows you can break - her heart. So don't hurt her, don't change her, don't analyze and don't expect more than she can give. Smile when she makes you happy, let her know when she makes you mad, and miss her when she's not there.
