Why is human nature so messed up that we only want what we're lacking?

There is this girl that constantly replies to my messages, she is available, she wants to hang out, but because of that I feel that there is something wrong with her and I am disgusted by her. There is this other girl who rarely replies to my texts, but something draws me to her and I think she knows her priorities and every time she texts me I feel so good and I want to be with her. What is wrong with human nature since almost everyone wants what they don't have.
