If you can make decisions for David in Ch.3, there should also be 3 decision strands in my opinion.
1. Where David saves his company and marriage by exposing the villains and Anna stays loyal to him (so boring)
2. Where David loses his wife to men (player's choice) and ends up taking revenge on the one or those including Anna.
3. Where David accepts Anna's cheating. Although he hates to see or see how she is being inseminated by someone else, he swallows his pride to enable his daughter to have an intact family.
