I won't succumb to mischief - as my dad jokes, 1) ask for a current bank statement.

Unfortunately the only person I can call a true soul mate is the same gender so there's nothing physical in it. But:

1) Candour and honesty with me, for which she receives the same from me.
2) An optimistic and positive response to adverse situations;
3) Support in times of trouble (if circumstances make it possible) for which she gets the same from me.

If one has an affinity with someone these things will be there plus a few others. That's what soulmate is about to me.
Loves of my life? They come and go....

I think I'll pass on vibrational shifts.
