Just thought I’d add the definition of OTRS in case you don’t read the link:

OTRS is a normal response in neurotypical (NT) people as a result of prolonged traumatic stress in an intimate relationship. Symptoms are similar to those seen in people who continuously, for a long time, are exposed to emotional and psychological torture, both mental and physical. The impact is more serious because the traumatic stress, OTRS, is suffered at home in an intimate relationship, and because the surrounding persons typically deny the reality of what is taking place.

The damage to the NT spouse and children occurs insidiously and can continue for decades.
