One thing blue pillers and red pillers have in common is they think "texting game" is important. They think if they're witty, funny, cool, etc. enough in their "texting game" that can overcome looks. When conversations fizzle out and she leaves him on read, he always thinks he said the "wrong" thing.
Meanwhile good looking guys don't have this problem at all. Women text them enthusiastically and conversations happen easily and naturally.
If you're doing all of the heavy lifting trying to text or carry on a conversation, and she's only giving you one word replies...she's just not interested in you. (yes yes "water is wet", I know).
