In all my years of doing readings, I can assure you that at least 80% of them were love readings. I have had the blessing and the curse of being the energetic interpreter and messenger for the true nature of relationships (be it a karmic, soul family, or other).
More often than not, when a relationship is failing/ending the issue is more of an energetic incompatibility than an emotional one. The love is often there yet the frequencies of the people involved are no longer matching.
