The question isn't whether or not love and fate truly exists, it's whether or not you are willing to give up enough of your pride to actually experience or notice these things. Its whether or not you are willing to make a compromise with the person you love to maintain both of your happiness.
Love exists in its many forms and it will always grow and fade. Its something you need to care for and tend to, and it's something you need to allow yourself to feel. If you do not tend to the love you have, then at the end of the day, was it truly love at all?
The answer to that question is yes, it was, because like everything else,, you can lose it if you do not care for it, or you can lose it by placing what you cared for somewhere you typically don't. Like the arm of the couch or a counter in the kitchen. The only difference is, you will find the item you cared for a lot faster than you may find the one you didn't. Or heck, you'll feel a much greater sense of relief once it IS found. So if you ever do lose love or lose hope, or even lose faith,, did you ever really care? If so, work towards it, for you may find it again.
Now in regards to fate, as I had mentioned earlier, that's typically up to the querant as to whether or not they truly believe.. however I've noticed a trend. Those who believe, think it affects their lives down to the very second, and those who don't? Well I believe that's obvious. However has anyone ever thought to sit down and consider the middle? That yes it exists, but it does not dictate every moment of our lives. For round and round the wheel may turn, but at the end of the day, it's outcome isn't always predetermined. Fate is both random chance and determined consequence. I've also noticed that fate only really seems to determine the things that have the most impact on your life. The things that teach you important lessons or introduce you to important people.
Anyways, these are just the musings from a random girl who's laying in her room on a rainy Friday evening,, so in the end, what do I truly know?
