Marriage and No Penetration

Why?

 

He cheated on her for years. She is punishing him by cheating on him for years while keeping him in chastity and they aren’t having sex. The only reason they are staying together is she controls the company he works for. That sounds awful.

 

Awful to some, maybe, but very fair. Also, she still loves him and cares about him. If she didn't, she would have dumped him. So there's potential in this relationship.

 

His punishment sounds like what I've always wanted in the way of permanent caging. I figure he's a lucky man, but I wouldn't want it to end, even after almost 5 years of chastity.

 

To each their own...

 

Not a relationship you'd recommend to anybody, but we can understand how both of them feel and what it might be like to be in each of their shoes. If they are both happy that he deserves the penance she's set for his misdemeanours and it works for them, who are we to object?
Can you not see it as their way of repairing the relationship? Surely that's better than both losing all the other things they've created and want to keep in the relationship. What they each do at the end of the period will be significant, but we can't pre-judge either of them for that yet.
