This really connects. Can I ask - did you notice the career problems starting before you consciously recognized them as your twin, or only after the full recognition hit?
In my previous relationships (karmic ones, as I now understand them), my career actually thrived because I poured all my energy into work to avoid the emptiness I felt with those partners. I mistook that avoidance for ambition. Now I think about it, that might be a good sign of false twin flames to look for.
With my TF it’s been the complete opposite. My soul suddenly refuses to let me use work as a hiding place and is demanding I align with my true purpose instead of just “staying busy” for the sake of it.
