The dictionary definition of love is and i quote "an intense feeling of deep affection towards someone or something"
I cannot put the definition of love in a mere one liner sentence, nor could i explain what its purpose is, but what i can say is that love isn't just a word. It's a feeling, an emotion.
Let me put it this way when i say "I love you" i don't just mean i have feelings for you it actually means a couple things, such as
i dont want to be with out you.
i wouldn't ever want to imagine a life where i haven't met you.
