8H saturn transits and karmic partners

So I recently met with an astrologer and they told me how Saturn currently transiting my 8H will bring karmic partners; however, I was also told this back when Saturn was transiting my 7H in Pisces. It was actually crazy how this played out in my chart as I had a long term relationship spanning the entirety of Saturn transiting my 7H and we broke up not long after it moved into my 8H. But now I’m being told that it’s just another 3 years of karmic partners as Saturn goes through the 8H ?? I’m curious where this perspective comes from as I feel like the idea of Saturn transiting through the 7H makes sense as that relates to long term partnership, but the 8H doesn’t focus as much on it. I also personally feel like the idea of “karmic partners” can get kind of overused in the pop astrology world, but would love to hear personal takes on this!
