Thai girls aren’t much different than girls from other countries, they get jealous. What makes a girl Jealous depends on the relationship also, but Thai girls are known not for just being Jealous but for getting crazy about their jealousy. Some say Thai girls are extremely jealous because there are so many other girls out there that would love to be with a foreigner. However jealousy among Thai girls isn’t just for those girls with Farang boyfriends, I’ve seen Thai girls being jealous about their Thai husbands and boyfriends as well.
So where does the jealousy among Thai girls stem from if it isn’t just because your a Farang with money. In Thailand it’s very common for guys to have a girlfriend on the side or a Mia Noi (second wife). Thai girls are very aware of this and some put up with it but some go out of their way to make sure their boyfriends can’t have another girl at the same time though she’s probably cheating on you or her boyfriend.
