Yeah, the TL;DR here is that people who think they are in separation with their twin flame can absolutely be in a toxic relationship… but that’s not really their twin flame.
It might be karmic, but it is most likely they just don’t understand the true meaning of the journey.
The twin flame belief that someone “completes” you is actually backwards. Real connections encourage you to be more complete on your own. If you’re finding that your entire identity is wrapped up in this person, if you can’t feel okay unless things are good with them, if you’re giving unconditional love regardless of how they treat you - that’s codependency, not soul recognition.
There’s also a distinction between healthy triggering and abuse masked as triggering. In actual growth, both people take responsibility. You feel more confident over time, not less. You can still function independently. In toxic situations dressed up as spiritual work, there’s constant criticism framed as “helping you grow” you feel depleted, you suppress your own needs.
