He asked me for a financial help. Did I react the right way?

Long story short - I am seeing a guy for 8 months long distance and he is in arranged marriage for almost 10 years now but lives and works far from the village wife lives in ( he is from a conservative village in Asia ).

He asked me about a financial help which I refused to give and I said that I can’t help him support another woman he is legally with automatically by helping him.

What is between us is between us but I don’t want to do anything with his other life anyhow.

Do you think I made a mistake or I should have given him money?
