Tell your mother-in-law a fortune.

Yes, after all, they only have one son, and sometimes parents' love for their children is a bit difficult to understand. But let them do the math themselves.

Anyway, the result is two, one is good, and that is of course the best.

One is not good, just look at their family's reaction. If you strongly object, it is better to have a long pain than a short one. Otherwise, you will suffer from marriage in the future.

Or you can fight to the death and finally beat them completely, but this road is not easy.
