Look, in this society, the only way you can get married is you have to be willing to burn it all down to the ground. If you aren't then you've lost before you start. If you can't burn down everything you've built then don't get married. Because if she thinks she can get something she will.
As an aside, I had never heard of Udemy. I've just spent an hour looking through there and just bought a course. Not the topic, but thank you for mentioning that site.
