very well done
I dont know whether this is the direction you were going, but I think that the girl herself was something that you have been looking for (your water). You have the boat (your life) but it is not complete without the water to make it float but once you found this girl, maybe fell in love, she brought her own boat (her life) also without water. After you found each other, you were both complete, and thus, the water. I think thats what you were going for but I dont know, correct me if I'm wrong. But other than that very well done sir.... or maam
