Like I said, you are wrong. I've lived in Buriram over 21 years. I came here to teach for 3 months but decided to stay. Now I've stopped teaching and live a nice, peaceful life with my wife whom I met here in Buriram whilst teaching. Many others I know have done similar.
Many that have come to live here with their partners are also very happy. Mostly sussing out the area before making commitments. I'm sure there are those that have made mistakes but that is a small minority.
Buriram and Korat are busy places. They have the facilities that other places, such as Chiang Mai, have. I live away from town for the quieter life but close enough to be near to what I need.
Buriram also has good bus, train and air links to Bangkok and ChonBuri, if that's what you want. Also only 3 hours away from Siem Reap.
Happy Days.
