In the previous post I attempted to describe a man who, as far as morally possible, related to his family in a manner analogous to the manner a Christian relates to God, so that even things that normally are not incompatible with marital love would exclude it.
We could also consider a more realistic case, in which a man's fight with his wife isn't incompatible with loving for her. There are, still, individual acts that are quite incompatible with love for her, e.g., attempting to kill one of their children, or signing over all his property to another woman for whom he has strong feelings. In this case, too, it's psychologically not possible for him to go rapidly back and forth from loving her to performing such acts incompatible with loving her, unless those acts are not really voluntary—and are performed only due to being drunk, for instance. Such acts that involve breaking off his love for his wife in most cases only complete and manifest a process begun long ago, of failing in love for her.
