Now that u mention your term boyfriend who still took care of you in thailand, i think that is one thing that i noticed early on when comparing asian culture and western culture. Older generation are greatly respected in asia. We give our money to our parents, grandparents, so your ex taking care of you while very sweet, not unheard of here. Itll be very hard to find retirement housing or community in malaysia, and i bet in thailand too, except for those catered for expats/foreigners as most of the parents/grandparents, live with their kids/grandkids. There are house by the goverment for those who needs it but its not a norm.
Now, im not sure about spain, argentina nor brazil about this culture. Money speaks everywhere though, so as long as u have them, im sure its not an issue hehe.
