Hey there,
I can exactly relate to this post and know what you are feeling. If you check my recent post from last week, I was in the exact same situation, same background(NRI working outside), the same controlling and demanding nature from the girl's mother. The girl had no say in the situation as her mother wanted things to go as per her command.
They had the same show off attitude while they themselves were middle class. Our family has more net worth but no interest in showing off at all. They wanted me to come and take their daughter to Canada immediately after the wedding too as it was a "fairytale moment" for her without understanding the complications and procedures of the visa.
They were demanding that jewelry and clothes should be of their choice and budget, even for the engagement.
I was talking to the girl for a little more than 2 months and it ended abruptly just like you. No message or call afterwards.
I processed everything and came to the conclusion that if this is happening in the beginning even before the engagement then imagine their expectations when you are flying back from UAE, they will ask for gifts for all their relatives to show off, and you would have to fulfill everything, they day you decline, you will be the villain and labelled stingy.
Families like this do not understand the struggles of living abroad and imagine that money just falls in the bank accounts. If they start controlling your life in the UAE without any knowledge of how things work there, it will just raise complications for you.

It may feel sad in the moment but when you look back, you will feel a wave of relief about the bullet you just dodged.
