I would think there are quite a few things and I'm sure posters will come up with most of them. I'll mention that previous experiences on both sides may have some bearing on it or help a bit. Many Thai women, who are happy to entertain having a foreign husband, are likely to have had negative relationship experiences previously with Thai men at some point, plus finding a suitable Thai man is actually quite hard and there are often philandering issues. Many Thai women also mention that western foreign husbands are just a little kinder and most respectful of them.
Foreigners who marry Thai women may also have had negative previous relationships (divorce/costly separations etc) and I have also heard many foreigners say they like the simplicity of the relationship the have here with an Asian woman, must be a breath of fresh air for most.
An Asian woman that is happy and loves her husband is a master at making her man feel appreciated and wanted.........goes a long way that does, and can be hard to find.
A foreign husband often represents a level of consistency that may have been lacking in the woman's life before, not just financially but emotionally too, plus the future appears a bit brighter than what they are used to, I would guess. Good men are just as hard to find as a good woman.
As far as the guys are concerned........well, maybe it's a style of relationship that they have always liked the idea of, but has perhaps disappeared in the majority of societies in the west. It represents a chance to start again and move on of what has gone before.
It might be worth a mention that, together, quite a lot is possible in a mixed culture marriage and does have much to explore and find out.
Just a few things other than the obvious ones that get mentioned all the time.
I'll leave the floor for others...........
