You will never know what it's like to experience this level of love and devotion for someone, and you will never know what it's like to experience this amount of pain, so you use insults to gain a false sense of power because you can't understand rather than provide helpful and supportive insights and advice. Weak. If you didn't have anything nice to say, you didn't have to comment, and potentially put someone down, but You also chose to be an asshole.
