Make her stay

She's not meant to be perfect. Neither are you. We are wretched beings. Flaws have gradually become a part of our DNA. Human flaws. One of the excuses why we tend to hurt the ones we love the most, either through words or action. Irrespective of how much you try not to, you'll end up doing the same. Every single time. It's written in the comets. [Stars don't move nor care about you.] You can't really edit the screenplay but you can work on it. You can work on yourself. Make it happen. Convince her to stay a bit longer than she's planning to. She may love you to bits today. She may not day after tomorrow. She'll grow tired of who you really are. She'll wake up someday and feel suffocated by your presence. Because, like you, she's imperfect and decorated by flaws. In the end, what matters is contentment. If you're lucky enough, you'll fall in love with her flaws, thus completing yourself. If that happens, she'll wake up to kill you one night in your sleep. But then, she'll kiss your forehead realizing she can't possibly bump into a bigger fool.
