I used to think like this until I started dealing with ppl, platonically and romantically, who were secure enough to be genuinely kind. if you are mean to me or I have to be mean to you for you to respect me as a human, you're a loser to me and you will not be in my life
I think people truly underestimate how hard it is for two human beings, to do LIFE together. The amount of effort, compromise, understanding, trust, loyalty, honesty, resilience, love, care etc, etc, that it takes. You have to CHOOSE that person every single day.
