I am shouldering all the expenses for our wedding? No way!

I am marrying a Filipina woman and I can't really believe that I am the only one shouldering all the expenses for the wedding. I get that I am a foreign man who is quite well-off in life but this is just outrageous. I am used to having the expenses divided by both the groom and the bride because that is how it is in my country. This is actually a violation to my own belief and I do not know if I should still go on with this wedding.
