What's the point of being around people if you have to be entertaining?

I'm becoming more of a psychopath everyday because I am understanding more about life and the way people are. My dad abused my mother and my mom would take it out on me. My mom only loved me if I helped her out on things and she would say she hated me when I made her mad and that she wished I never existed. Around people, it's sort of the same thing. You can get friends if you STAY entertaining and fun to talk to. As soon as you stop, people will sort of drift away from you. This happens in a lot of relationships to. Women or men will cheat on their spouse if he starts to bore them or starts to complicate things in the relationship. No one is unconditional, they always want to be around someone who is entertaining and amusing. So humanity is nothing but a piece of **** because love never lasts long. So right now I am in a confused stage trying to understand life without humans. What is your take on humans and human nature?
