Roots.

You have rooted yourself within me and I within you. And roots don't fall out easy though the tree is tossed and toppled by the wind or storm. Your roots have managed to hold my heart so strong because you have taken all the time to dig to the deepest parts of my heart and plant yourself therein. Now if you plan to pluck yourself out, you know the consequences. Any plant while pulled out, will take some soil along. But my heart is a very small place and you have conquered all. Every corner. Your roots will drip my blood and soul if you pull yourself away & a part of me will always be yours. But maybe it is the right thing to do, when you're planted in the wrong place, the wrong heart. The heart realizes or the plant does, whoever, must suggest removing the dear plant. You are a sapling my dear and you need to grow into a big large gigantic fruitful tree. And that will not be possible when planted in the wrong soil.
You are the perfect plant and I'm the imperfect soil. :(
