You are really in love when you suddenly realize that you and your partner are one. In such a mood, you will not want to hurt that person. Doing that is like doing that to yourself. You will want to share your best food with that person, since you will have the feeling that their fulfillment is yours as well. All you think about when you are in love is how to make that person happy. It is the only way you will be happy too, since both of you are the same. It is this feeling of being that person that makes you want to spend the rest of your life with them because you seem completely inseparable. You seem hooked.
