Every love story is different. Sometimes, it can be quite amusing at first. You get addicted at the feeling of being in love, then you'll get tired of it and can't seem to stop feeling the idea of it.
You will feel the need to let go of that person you really love because it's the best way to prevent conflict, to prevent being hurt and most importantly, to prevent your soul from harm.
It should be protected. If your soul is fragile, you should protect it at all cost. Never let someone break it or you'll be lost, you'll never be you again. It'll change you and it will go worse.
