Although it is early for you to really bother on the marriage front as you still have your education and career that you should have on your mind, but I believe that it can be due to your curiosity. The sign of your spouse can be varied but your 7th house in your horoscope is ruled by Mars as Scorpio sign is posited there. Mars is posited in the 10th house with Ketu and Jupiter, indicating that the person will be well qualified and highly educated. The native will be a professional. Mars is exalted in Navamsha indicating that your overall married life should be good. Scorpio born people are bold, strong and highly independent. It is the female sign of Mars and these people can be secretive and reserve and don’t open up very easily. They can be highly stingy when it comes to spending money, they tend to have a jealous nature.
Even if you dont have any planet in the 7th house , it does not matter. The sign in the 7th house and its lord is important.
