I once dated a man I had a karmic link with. Usually, karmic relationships are the purpose of teaching you certain lessons so you can balance your karma. Once the lesson is learned, the relationship organically dissipates and you're both set free.
This is what happened for me. We were on and off for two years, once my lessons were learned, he disappeared. I no longer wanted him in my life.
It doesn't mean you stop loving them, it just means you no longer see the point of being with them.
Karmic relationships might make you feel like you've met "the one" (at first) but once the issues are settled, you end up wondering what drew you to them in the first place.
Good luck
