Mars in 8th house makes the Ashtam Mangal dosha. However in your horoscope there is no Dosha as Mangal is conjoined with Jupiter. When there is aspect of Jupiter on Mars or Mars and Jupiter are conjoined in 8th house then the Mangal dosha gets cancelled. Do not worry you have certainly marriage in your horoscope. Do not get carried away and tensed because of some people. As a Matter of fact there are strong connection between Rahu, Lagnesh Venus, Mercury which is the planet of intelligence and the 5th house indicating love marriage. However I will advise that you do proper matching of the horoscope to get marital happiness in your life.
