Hate and love can be very closely related, and the line separating these two emotions can be very thin. Love can quickly turn to hate when a romantic relationship breaks up, and this is also true when a beloved friend or family member betrays you. If you feel hate then you need to forgive the person and let this emotion go before it hurts you even further. Love is positive but hate is negative and destructive.
I can't hate people for making judgment on me, or making a decision of liking me or not liking me. All I can do is try to better as a person. And I'm good with knowing everything isn't always going to be perfect.
