Ans: Veritatis Splendor has largely been ignored pastorally.  It did not change practice that predated it.  It is intrinsically evil to abandon one's spouse and marry another because that other is hurt.  It is not intrinsically evil to escape physical or sexual abuse and marry another.  It is not intrinsically evil to agree to end a marriage by mutual consent and marry another.  It is not intrinsically evil to leave an alcoholic, addict or mentally ill person who rejects treatment and marry another.  Evil happens in relationships, not in some mysterious natural order that is a sophistry designed to get past the fact that God cannot be hurt by sin.  Neither is the Church harmed by remarriage, unless it ratifies remarriages by serial abusers, adulterers, etc. by granting annulments based on the original marriage and not on subsequent behavior.
