For me its not that the husband loses, its that the story is dark and had betrayal, that means, yes, that the husband loses and the troll wins but that makes it more exciting to me, when there is a realistic betrayal that builds. Stories that have the husband treated like crap over and over and over are actually repugnant to me. If you are going to write a wife character who hates on her husband 100% of the time and love on every one else, then why did she marry him? Example: Executive Decision. While well written, my problem is that she is falling into the same tropes that the guy's ex-wife did and swore she would never do that to him. She loves his intelligence and kindness and yet she has started looking down on him because of just that. I get it, he is a numbers guy, but she knew that going in and now it is just so easy for slime that she hated to supplant the husband due to his seeing her as a sales dynamo with the ability to see the advertising picture. She is Don Draper in Mad Men, following the man who is her new svengali. Her Husband is Peggy on Mad Men and now Don, who used to love Peggy now sees her with derision. I wish that, in a lot of ways, that Executive Decision would wrap up in chapter 10 with her apologizing and asking the husband for a divorce. They split up, he quits and finds a job somewhere else, the NY Yankees office as a statistician or something else that will see him have mondo success away from her. Then she can be successful and have a great relationship with her boss. At least it wouldn't be that uncomfortable a read ten chapters from now, when the husband gets hit again and again and again.
Betrayal that builds from a plotted story = good
Treating a husband that does the wife nothing but good like trash repeatedly due to an asshole getting involved = bad.
IMHO.
