Love is an emotion, it can fill us up or empty us out. Love is one of the few emotions that we can not always choose who we give it to, it has a life & mind all of its own.
Love can be fickle, play on our fears, or bring out our strengths, it can last a lifetime or just a month. Love is that feeling, when you touch someone you love in a intimate way, you can not get enough, the sound of their pleasure feels almost as good as your own.
The only surety with love is emotional pain & happiness. When you love you know at some stage you will be hurt, no matter how happy you are, it may not be intentional, sometimes all it takes is careless words spoken in anger.
So is love perfect? Yes it is the perfect emotion to drive us to be better, however no, it can cause such distress you can barely tolerate it.
Maybe in the end, it is perfect for a lifetime, as you learn more about each other, tolerate those little things you dislike. Maybe love was not meant to be short term.
