You seem like you understand the internal native of your feelings. The guy in article does not.

The proper response is, "I feel terrible that she's not texting me back. But, it's not, in fact, terrible. I can handle it. I'd rather she did text me back, but there's no rule that says people have to be interested in me. I may very well meet someone soon that is interested in me as much as I am in them. I had better do something today to try and meet them instead of sulking."

The guy in the article is more like, "How dare she not text me. She's not even good enough for me. She's old and not that hot."
