Hi,
Please bear with me (my understanding and opinion of your birth-chart) and feel free to ignore anything that is not to your taste or liking.
In my humble opinion, there are limited yogas for marriage in your birth-chart. On my part, I wonder if you are truly desiring of company and relationship… for I’m inclined to think you are somebody who prefers to be by yourself and you are probably asking due to family and/or societal pressures. There is a strong footprint and undeniable influence (direct or indirect) of Ketu, that has contributed to the current situation – more so with Lagna Lord Jupiter/Guru-dev, Mercury/Budha and Venus/Shukra. This seems to be pushing the birth-chart towarads denial. If you are truly desiring of a relationship, it would make sense for you to consider offering special prayers regularly to Lord Ganesha, with unwavering bhakti/devotion and a strong sankalpa. It is also said chanting Rukmini Vallabha Mantra will help the cause.
On the sidelines, 7th lord of Kalathra-Sthana Mercury/Budha being placed in the 7th house (where he is neither happy nor comfortable for related significances) is not preferred nor is Venus/Shukra (calls for validation of Karaka-Bhava-Nashaya), more so since he seems to be very closely conjunct Ketu… in fact to the extent of being in Graha Yudha or Planetary war). Thereafter, I personally don’t like presence of Sun/Ravi the 6th lord in the 7th house.
Take care…
