You said that all this trauma happened when your wife was young and it didn't seem like anyone got her help at the time. I have a feeling it's been simmering for awhile and your w didn't have the tools to cope with it in a healthy way.
Mlc happens when a change in attitude happens after a big life event trigger.
Your w's fatalistic attitude seems to be a side belief ofher thinking that bad things will always happen in her life.
You have to approach her with that understanding.
