IN all practicality so far as living in Singapore is concerned,
in such a scenario, going ahead with the marriage is a bad idea.
However, it is believed and proven that LOVE can indeed overcome
immeasurable difficulties. So, I'd say this answer to your question
is very subjective, depending on the priniciples & commitment
of the parties involved.
Personally, I WILL still carry on IF I have the financial means to
support a bed-ridden wife. Otherwise, I'd still stay in touch, and
contribute financially on a regular basis.
Mindful also, that there will also be technical complications in
the areas of Insurance policies.
