I have had a similar incident in my neighbourhood.

One deaf and dumb son of a rich manwas engaged with a lady from out of valley. The lady knew his disabilities. The guy is one of the most respected in his circle as he is a teacher of sign language and is really good looking. The guys family knew very few about the gal. As they were happy that a normal gal agreed to marry their disabled son. But a week after the engagement, the family heard the gal was a highway prostitute. They tried to find the reality. And what they heard was the truth.

They wanted to terminate the wedding. There was a big dispute among two sides. The gals side was very filthy people to deal with, as I saw them swearing publicly. It was hard for the guys family to handle that. Finally they paid a ransom of 1 Lakh and terminated the wedding.
I still feel bad for that nice family and the deaf/dumb gentleman, who I respect as well.
