think the astrologer mentioned something about a pluto-uranus(slow planets) cycle & jupiter also having some influence though i'm not quite sure..plus the transit was supposed to last 59 days.
Pluto takes about 246 years to complete a cycle of the Zodiac, whereas Uranus takes about 84 years. So you won't live through even a Pluto opposition to it's natal placement. On the other hand you may well live through an entire Uranus cycle.
If you take a cycle between conjunctions between Uranus and Pluto, the last conjunction was in 1965 -66 and the one before that was 1850-51. So we're talking about sextile, Square or Trine. Given that a lot of Modern Astrologers associate Pluto with power and transformation and Uranus with Revolution and Eccentricity (though it's actually Pluto that has an eccentric orbit).
Now this is where I think your Tarot reader it taking their description of powerful change and extra-ordinary events.
What I don't know is if the Tarot reader was referring to this as a 'live event' or whether the reference was to transiting Uranus aspecting natal Pluto or Transiting Pluto aspecting natal Uranus (which depends a lot on your age.).
In terms of the event. There have been seven squares between these planets between June 2012 and April 2015 - so if this is what was referred to the event should have occured by now, though if a fairly wide orb is used, then they may still be treating the square as being in force. The same interpretation may well be given for the aspect between transiting and natal planets.
My feeling would be that it's the 'live' event which they were referring to but I can't be positive.
Jupiter would pin the time down more closely. Jupiter's cycle is approximately 12 year, so it spends an average of one year in a sign. or it moves just over a tenth of a degree per day. 59 days would therefore be just under one degree.
It's not clear whether they meant transiting Jupiter or natal Jupiter. The last time these three planets were in exact aspect was April 2014, when Jupiter in Cancer opposed Pluto in Capricorn and Pluto squared Uranus in Aries. And it's configuration that I would think they are referring to. The month and year of your reading would confirm or disprove that (unless the reading was after that date and you'd already fallen in love).
But if it's that configuration of April 2014 that is referred to then there's another problem. Unless you gave them your date, time and place of birth, they had no way of knowing if this configuration had any specific meaning for you because everyone who was alive on that date experienced the same event - thats about 7 billion people and they didn't all fall into a powerful and extraordinary love.
I have to say that personally, I think Pluto is not the powerful transformative force that Astrologers see it as. Nor do I see Uranus as revolutionary, quixotic, and extraordinary. So I would not take it as seriously as your Tarot reader did. That doesn't rule out the possiblity of the prediction coming true under another combination of astrological factors. But without a natal chart there's no way to link you to this or any other configuration of transiting planets.
Without your chart I can't say more, other than I'm making the assumption that the predicted event hasn't happened, but that's based solely on your question and follow up.
