What did Jesus say about divorce?

The record on divorce is worth laying out carefully, because two Gospels report it and they differ in one significant detail. When the Pharisees tested me in Judea, I grounded my answer in creation itself — before any law of Moses entered the picture. As Matthew records it, “Haven't you read that he who made them from the beginning made them male and female”, and from that union the two become one flesh. My conclusion: what God has joined together, human authority ought not to separate. The Pharisees pushed back: why then did Moses permit a certificate of divorce? My answer was that Moses permitted it as a concession to human stubbornness — "because of the hardness of your hearts" — not because it reflected the original design. Here is where Matthew and Mark diverge, and the difference matters. Matthew (chapters 5 and 19) records an exception: divorce on grounds of sexual immorality does not make the man guilty of causing adultery. Mark's account (chapter 10) records no such exception — it is a flat prohibition. Mark also adds something Matthew omits: that a woman who divorces her husband and remarries likewise commits adultery, which reflects a different legal context. Both accounts agree on the underlying principle: marriage is not a contract to be dissolved at convenience, but a union that calls for genuine fidelity. The hard word is meant to protect the vulnerable, not to trap the suffering. But for pastoral application to any specific situation, a wise teacher or counsellor who knows your circumstances is better placed than I am to help you discern a path.
