Yup, and we are not insane, it just got worse and everyone observed it. Thailand (Bangkok in particular) got shitty because of many factors. However, I still had better success in 2nd or 3rd tier cities in Thailand. In Bangkok it was almost like being in the west. Girls were flakey, uninterested, low matches. That's when I realised that Bangkok will never be the same again (in terms of dating). I love the city man, but fuck it..
But in 2nd tier cities .. man, it just doesn't even compare to Bangkok. There I was the center of attention wherever I'd go. It was like I changed the fucking country. If you still wanna go to Thailand, avoid big cities like Bangkok, Chang Mai etc. Go for the lesser visited ones.. while you still can. Don't have high hopes for them though, it will just be better than Bangkok, but the country is oversaturated with tourists already.
