Hi,
In my humble opinion, there is a strong foot-print and undeniable influence of Ketu with regards to unfolding of Karma in the native’s life. Ever since end of Venus/Shukra Maha-Dasha (as per Vimsottari Dasha system) in late 2014 / early 2015, subsequent Maha-Dasha lords Sun/Ravi (from 2015 to 2021 for he is postied in the Lunar Constellation of Magha Nakshatra, ruled by Ketu) and current Maha-Dasha of Moon/Chandra (posited in the Lunar Constellation of Ashwini Nakshatra, ruled by Ketu).
Ideally, it would have made more sense for family and well-wishers (if they desired for the native to be married) to have considered suitable remedial initiatives earlier. Quite frankly, it may still not be a bad idea, although I’m inclined to think the native might be feeling a bit detached and prefers to be by herself. Incidentally, next Maha-Dasha lord Mars/Kuja also activates Ketu (who is posited in the Lunar Constellation of Mrigashira Nakshatra, ruled by Mars/Kuja) as also the subsequent one (Rahu is posited in the Lunar Constellation of Mula/Moola Nakshatra, ruled by Ketu).
Given her current age and personal disposition, not to mention the placement of Mars/Kuja (and his influence on her nature), it might not be a bad idea to let her be (request you to kindly bear with me and ignore, in case my suggestion is not to your taste or liking).
Take care…
