I've just been reading your "thanks for everything guys" thread again, so after reading it, I went to your first post about your ex-girlfriend. There was something that didn't add up to me and that was when you said that she worked in a massage parlour in Bangkok, was very attractive and spoke very good English, but it was not a boom boom establishment. I lived in Bangkok for 9 months last year and 4 months this year, without generalising too much, if a girl is very attractive, speaks very good English and then decides to marry an older farang whilst being your girlfriend, it is highly likely she was or still is either a bargirl or a freelancer! Most of the non naughty massage places in Bangkok are staffed with older ladies and gay men, there were lots in a mall near where I stayed, their English was quite limited as it was a mostly Thai area. Thailand is littered with casualties, be careful.
I thought your plan of teaching English in Thailand was spot on, Bangkok is the place to teach. I have two friends teaching there and they earn 42000 baht and 65000 baht a month respectively. If you really want to find your dream Thai girl, then you need to live and work in Thailand, take a year out from work, do the TEFL or TESOL course in Bangkok.
The UK is a dreary and grey place for most of the year, apart from summer. A young man like you will find the girls in Bangkok that go to the smart/trendy discos, work in offices and have degrees will love a young farang to be with.
