Can Buddhism change when marriage is not smooth?

It's hard to change

To understand a truth:

Everything that is extraordinary because of karma has long been decided.

Fate will come sooner or later, and marriage has its length, so don't be so persistent! Everything is natural. All right!

Practice is not about seeking the quality of marriage, so being too persistent is equivalent to seeking happiness.

Everything is born by karma, and it is also destroyed by karma. What's the use? !
