No, it makes the husband a liar. The sacrament is still a sacrament regardless of whether afterward the spouses honored their vows or not.
The whole thing with annulment or decree of nullity isn’t that it makes the marriage invalid or says it didn’t happen. It says that at the time of the vows (not afterward) the people making the vows for some reason were not capable of understanding or consent, either from their own fault or from a spouse not giving them information which they knew of and which would have kept the spouse from marrying them.
A shotgun wedding could be invalid because the groom did not consent of his free will.
A marriage of two people, one of whom knew he or she was a compulsive gambler, drunkard, etc. could be invalid.
BUT. . .two people who were free to marry and understood consent, but later the husband (or wife) got ‘tired of’ the spouse, or turned to drink after never drinking in the past, probably will not be invalid simply on those criteria. It sounds harsh (and those of us who have been through the process know there is always a chance that the marriage will be held valid, and have to be prepared to live with that validity even if we don’t live with the spouse having divorced)= but it truly is not.
Remember, if your spouse is assaulting or otherwise abusing you, you don’t have to stay. And a divorce will not be ‘your fault’. It is rare for this kind of case not to be granted nullity because people do not usually suddenly ‘change’ in adulthood so drastically and it’s likely that John the wife abuser as a man was Johnny whose parents and teachers saw him bullying others. . .meaning, the abuse propensity existed before marriage, etc. etc.
God is not ‘more forgiving’ in the sense that ‘The Church says no” but God will then say, “oh forget that, I say yes”. There is such a thing as presumption (a lot of people want to presume that God, understanding how special they are, won’t hold them to ‘rules’, and God won’t forgive somebody who doesn’t even ASK for forgiveness, though if they DO ask, God would even pardon Adolf Hitler or Theodore McCarrick whereas ‘man’ would consider them total losses with NO chance of forgiveness. But forgiveness must be asked for.
