So you have asked so many questions, I don’t know which one to take first. You want to know if 7th lord in 8th in D9 will kill your husband. No this is totally absurd. You may have read something somewhere, but you cannot apply the same thing everywhere. Astrology has a lot of combinations and possibilities, just because of one placement of planet you cannot reach such a conclusion.
3 planets in your birth chart are combust. So the planets which get combust are weak and you will have to strengthen them to see their results. Lastly, do not get married because your parents want you to get married. Get married only because you are in need of a life partner, a companion. Your parents can help you in finding a good partner, but eventually, it should be your decision, else you will never be happy in the relationship. And not to forget to mention that negative thoughts come to mind when you lose hope, are unhappy and helpless. Use meditation and yoga and learn to relax yourself.
