Agreed, Husband was neglectful and shitty to his wife, no matter what he was doing.

Also stupid. A side issue with this whole situation with the way Husband and Cousin’s Wife set it up… Very often when someone suspects their spouse of cheating, they call the spouse of the affair partner and let them in on the secret. If LW had called abusive Cousin to spill (what she thought was) the beans, it could have gone very badly for CW and/or Husband.
