what are the obstacles in marriage?

speaking as a hispanic in america, i've only seen marriage in my own family has toxic. a sense of purpose is lost and everything became personal; my parents, grandparents on both sides, and among my aunts and uncles.

i would see stable marriages happen anywhere else.

in arab-christian communities, do dysfunctional relationships exist? how are they mended? are they ever mended? what's the experience and customs for christian marriages and divorce?
