When you are in love with the wrong person or in a relationship with someone who does not have the same level of sensitivity and intelligence as you and doesn't care for you enough, you must use your logic in order to get rid of this feeling that is not good for you.
There are so many people in this world! Why do you insist on loving the wrong person?
I know it doesn't depend on you, but you must help the situation agreeing on paying attention to your reasoning.
