“Inger was emotionally fragile. Fell in love with every leading man she worked with. That’s a lot of ups and downs.”
Sounds like trauma or a type of PTSD. From what I have read (along with a boatload of mandatory college psych classes), it’s not an uncommon trait among those wishing to cause self harm as a result of their low self-esteem stemming from unwanted and forced sexual experiences in their youth. You see that a lot in hookers and strippers as well.
Yes, earlier abuse is a clear possibility or even probability.
