I most certainly did. I read on forums like this one all the tales of woe and what to be careful of. To balance that out I also read a lot about the good Farang-Thai relationships and formed my own opinions. Like many I did the bar girl thing, banged as many as I wanted and honestly got bored of it. Even then I still made mistakes but to be honest they were small ones in comparison to some.
Before I retired from the military I did about 13 trips to Thailand and travelled well. I saw everything I wanted to see and still left myself plenty to see/do. Just before I actually retired I did a basic two week language course in BKK as I knew for certain I was going to retire here. Whilst on that course I met a lady in a furniture store of all places took her out for dinner and we have been together ever since (almost 8 years) and I married her in May last year.
So what did I actually learn? Well I learnt to take my time with Thai women and really get to know them. There are so many beauties here it can be really overwhelming to get so much attention. I learnt to carefully control the flow of money and not be taken for a mug. What I get from my military pension and what I had saved are not things that women ( my now wife included) need to know.
I learnt and this is a biggie only spend what you can afford to lose for example my wife had some land and I decided rather than renting I would build a house for us. It’s not a sprawling mansion but something that is perfectly adequate for two people to live in. I offered her 1M baht and let her get on with it( she got the price in at 965,000 baht in the end). I learnt to not show the builder that I am a foreigner ( I never went near the house during the build everything was handled by my wife). No money was given to any Thai except the Mrs when buying materials for said property and I learnt not to let family (hers) be involved in any part of the building process.
Forums like this, in my opinion putting all the BS aside can be a wealth of information but you have to balance out the good with the bad and it’s not just with relationships it’s on any topic really. I’m sure there are many more examples out there but for sure I have definately learnt stuff.
