In your horoscope, we see that your lagan is Sagittarius and 7th house which is the house of spouse is ruled by Mercury as Gemini sign is there. Saturn is placed in the 7th house which is not good as it brings delays and obstacles in marital life.
Gemini as is ruled by Mercury are known for their adventurous spirit and love of freedom. They tend to be spontaneous and enjoy exploring new ideas and experiences. In a relationship, they may need a lot of independence and space to pursue their interests, but they are also loyal and committed to their partner. They are optimistic and positive in their life. They enjoy life to the fullest. They do not like restrictions and limitations, therefore if you try to restrict them they will revolt.
Due to Saturn in the 7th house, it is not necessary that your wife will be elder to you. As Mercury is the prime planet representing your wife, she will be younger to you, although the age difference may not be much.
