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 is not perfect. you arent either, and 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 on to her and give her most you can. she may not be thinking obout you every second of the day, but she will give  you a part of her that she knows you can break her heart. so dont hurt her, dont change her, dont analyze and dont 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 is not there.......
