More than half the girls can speak English and many are interested in meeting foreigners.
Online prostitution on Badoo is, unfortunately, a problem.
I once wrote a review about dating Indonesian girls and where to meet them.
You can still read it here: Where to meet Indonesian girls?
The fact that they are looking for a stable relationship does not mean they want to get married straight away.I recommend you to update to the premium version though (only 25$ per month) as it will allow you to send an unlimited number of messages.It will also give you the edge compared to the other guys in terms of visibility.It still has a large number of users though: I checked on 15 December 2016 at 7pm and there were 522 women online in Jakarta (vs 537 on Indonesian Cupid). Badoo attracts 99,9% of Indonesian girls, from all background.You can filter girls by age, location, status, body type, etc.
