Firstly, Singapore men shouldn't get married. Just screw and dump. If you have a kid together, just give financial support.
Why risk the probability she takes half of everything you own, and maybe more + decades of alimony? Stupid no brainer.
But if you really can't resist and need to marry, set the tone of the marriage early, during valentine, make it clear no such celebrations will be done.
Assert you masculinity, dominance and leadership from the beginning. Otherwise she can fark off and look for another simp.
