you're 33 and you have to follow your moms wishes? Most people in the rest of the world by 18 already kicked out of the house and will marry whomever they want. The world does not belong to our parents or their parents. It belongs to the future.
The solution? Show your mom that this girl doesnt have to be Chinese to steal your heart or for you to be a responsible man who can take care of his family. Show that everything you do, is colour blind and all you seek for everyone is happiness.

The media most people expose themselves to are out there to sensationalize everything. They have no interest in real news. Are only there to raise your eyebrows. The truth is boring and doesnt sell. Everyone out there talks about how you will need to "cut" it to be muslim. When the truth is no member of the clergy is going to ask you to take off your pants and prove you've been cut.

praying? the idea of praying is to seek inner calm by talking to god. Most religions out there have similar beliefs. Well, in your own house no one is going to storm in and force you to pray.

Halal? Authorities dont really care what you eat in your own house or if you go to other countries and eat pork. But if you eat pork or drink alcohol in Malaysia at least, they will feel challenged that their authority is undermined.
When everyone starts ignoring the law, "chaos" will ensure. (by chaos I mean peoples will start ignoring the authorities). When no one listens to the authority, they will start to lose their power. And no power, means, they will lose their job.
I've been living in Singapore and MUIS doesnt care what you eat. Their job is to ensure you have many options in terms of halal food and to guide Muslims.

Aurat? kind of a grey area. But imagine you seeing old uncles and aunties walking around in hot pants and low cuts all the time. Not that pleasant. So there needs to be a common understand as to what is decent clothing. Unfortunately malays are taking it too extreme these days. No one is forcing them to wear hijabs at all.

TLDR version:
When you're married, whether you're religious or not, there is actually only one person in the family you need to please.
That is your wife.
If both of you can come up with a harmonious solution to everything in your marriage, then you're set for life.
