And your point is? You made a claim that shopping addiction breaks up more marriages than infidelity .... which you didn't support with any facts. Plus you ommitted the many other types of addiction which can and DO break up marriages.
Now your tossing in arcane statements about how individuals deal with addition. Some spouses stay and try to work it out with the addicted spouse, and some don't.
The fact is divorce has many causes. In your (unsupported)assertion about shopping addiction breaking up more marriages than infidelity you seemed to condone a husband dumping the marriage. Do you condone the wife doing the same if the husband has an addiction?
What about in cases is infidelity, is this valid grounds for divorce?
