It also makes it easier to understand why she probably doesn't have an OM.
This is MHO about this and why some have OM's / OW's and others don't.
MLC is about returning to an age in their childhood where something has gone wrong and fixing it and then proceeding on with life.
So some go back to teenage years and some go back to an even earlier time.
Look what you wrote

So I suspect she has gone back to this time to FIX this.
Some with go back to Infancy(0-2) - learning Trust vs MisTrust Toddler(2-3) - Autonomy vs Shame and Doubt PreSchool(3-5)- Initiative vs Guilt Pre Adolescent(5-preteens) - Industry vs Inferiority
after puberty they could be Teens(13-20) - Identity vs Role Confusion Young Adults(20-30) - Intamcy vs Isolation.
This is taken from Erikson's Stages of Human Development.
ForeverYong this is all well before you even may have known her. She must resolve this herself, and there is nothing you can really do to help. Except to have understanding and to give her SPACE.
