The Tower reversed on loves indicates that Nadia will meet a person with whom she can have a relationship but it will not be the right one. It could be a short-lived relationship or it may not go the way she hoped. That means Aunt Nadia isn't very likely to meet the soul mate she's always wanted.
The Three of Pentacles suggests that Nadia will have more opportunities to make new acquaintances and meet interesting people, thereby increasing the chances of finding the right person. It also indicates that Nadia will have to put effort and dedication into finding love, and it's not just about luck.
In conclusion, considering the meaning of the two cards and the aspects indicated, the answer to the question whether Nadia will meet the soul mate she has always wanted is: No. Although there will be more opportunities to meet interesting people, the cards indicate that it won't be much likely to happen, unless Aunt Nadia is committed to finding love.
