The whole "dating" concept wasn't offered until he realized that people were dropping him like a hot shit for soliciting prostitutes. In his mind, he thought he could just say he was using prostitutes, blame his wife for not fulfilling his needs and WT for tampering with his sexuality, and it would all be fine. Everyone would be so sympathetic and supportive.
So, when he saw his support drying up left and right, he had to alter his story and suddenly paint it as if he was actually going out on legitimate dates with someone who just happened to be a sex worker. In Thailand. Where he was for a month. Because of course sex workers in Thailand legitimately "date" foreign men who are in their country for a limited time. But that was the only straw he could grasp at once he realized he could no longer BS people and count on their unwavering support. Uselss lying deceitful ass hat.
