The greatest bond we have on earth is the bond with our spouse. There is no mistaking that everything in our world, plus Satan and his demons, are trying to tear that apart. Divorce is not an option. God does not like divorce at all. He doesn't like it for any reason whatsoever. There seems to be some provision for divorce when there is abuse/abandonment and unfaithfulness with another person. But, even then, God would prefer it to be worked out and stay married if at all possible. No, you are right. This is not easy. It is very difficult. But by God's grace and both parties working towards the goal of honoring God, it CAN be done.
