This is the question people should be asking, but most of the people who will give generic advice probably aren’t able to stop chasing anyway.
If you stop chasing, it doesn’t mean the journey has failed. This is actually how you push things forward toward union.
To stop chasing, you need to do “surrender”. Some people think this is just another twin flame stage to “get through” but it is more of an active process, and there’s a really good thread on how to surrender to the journey.
That’s it.
Anything else is fluff and filler. You’ll be back here in 12 months, dealing with the same problem.
@Cassady wrote a guide on inner work for twin flames and this is the only thing that will help you move forward.
