Suspicious

Singapore turns lots of men into cheaters. https://www.expatexpert.com/infidelity-abroad/ It could be the willingness of women to exchange sexual favours for money or women falling for men with money. Men have it good here. 

Beware of Filipinas and Singaporean women. Especially if your husband is white. Beware of Mainland Chinese women if your husband is asian. East Asian.

I am told by other expat wives that expat life in Singapore can be the catalyst for a divorce. My thoughts on this are: if that's true, then the marriage was dead anyway. The trash just took itself out. Get a good lawyer. Good riddance.
