Maybe not. I got more info that this post reminded me I should update here. Thanks to @Ana333 for the nudge to sit down and articulate it.
Becuse based on this:
Well, yes, but.
Thing is, you can’t really banish yourself. You can’t run away from yourself: you’re always right there. You can fragment and suppress parts of yourself, but actually resolving issues like that takes shadow work and integration, not rejection. Another way to consider it is as a “soul fragment” under shamanic principles - same idea though, needs integrating to deal with it.
So if this had worked I suspect all I’d have done was suppress it anyway, possibly leading to more issues later.
I think I could switch the targeting - to dissolve the relationship between “her” the old me, and her obsessive attachment to the hubby she lost, wanting him back. She carries a lot of guilt with her grief. But as I said in the other topic, you can’t run away from yourself and now I’ve established an understanding, which has also increased separation, I have to integrate not reject.
Between us, I’m the adult in the room. I’ve had the benefit of studying concepts in modern psychology and magickal tools to work on understanding and processing what happened that “she” never had, as well as different cultural attitudes more supportive than in her day. So I’ll work on it from that angle from here.
