I agree with above and in addition would say that problems like emotional/physical abuse , husband not providing financially , husband not being mentally stable , cheating and inlaws making your life hell are good enough reasons even in the eyes of law for divorce.One reason that law does not account for but is so vital for marriage is TRUST when either of the spouse do things repeatedly that breaks the trust then it’s becomes very hard for the marriage to survive. But jumping to the D word over small small arguments can be very damaging for the relationship. Once said is okay because everyone can make a mistake once but repeatedly saying about divorce would only weaken the relationship.
Off course one can survive without marriage , and end of marriage/failed relationship is not an end to life but Islam says that divorce should be the last resort and one should try every possible thing to save the marriage.
It’s true with a sound educational back ground and a job it’s easier to walk out of painful marriage. But it’s doesn’t take a westerner to take that decision. When you are in a bad bad situation and wants to get out of it , it doesn’t matter if you are in west or east
