Now here is the problem when you say it's normal because the environment generalize it (classmate also consist of divorce parents).

In future, all these kids won't take marriage oath seriously. They can just sign the paper and divorce when they deem it fit.

Which makes me conclude that most of divorce case come from broken family background. their parents divorce, to them divorce is a "norm" too.

From my POV, I will never allow my child to have any romantic relationship with broken family kids. I nurture them well, end up become broken. what's the point then?
