I have an Javanese partner and the change that she was muslim (because of her family traditions) came tru. I told her from the beginning that there will not be any marrige and that this will be permanent. Her father and the mother had no problems with it as long as we are happy.
Did does not mean that there are no discussions about the stupiddity of any religions and that came in 2010 to a climax when she wanted that her latest son get circumcised. (the other two where allready victimised). I strongly opposed againsed the circumsising from her son because he is to young to oversee what it will mean and she has in my opinion not the right to mutulate a minor because of any traditional reason even when it is her son.
The family started to react but in an open way and they all said that it was because it should be like that because of the koran.
I also showed them the same link
http://www.quranicpath.com/mis(...)ns/circumcision.html
And because the were suprised about the content they started to discus the situation even more.
Never the less my partner desided to follow the wish from her father to follow the traditons.
When I asked her father why he let his daughters circumsised when they were a child even the koran does (also) not ask for it he culd not give any clear answer and just said that it allways was like that so he just followed the tradition.
That made my partner so angry and dissapointed in her father and also the other daughters were dissapointed that the discussion was tending to go in an other direction so I asked what she wanted to do now whit her son.
Simple, just follow the tradition and she did.
Even after the mutulation others followed in the family and even girls and that while there mothers know so much more now.
Conclusion: Love an Indonesian woman and get loved by an Indonesian woman andenjoy eachother , but never get married because it means nothing more than fullfilling a tradition.
