Mars is the planet of energy, it is the planet of initiative and courage. When debilitated it can represent the other side of Mars which is bring hasty, irresponsible talk, As Mars is in the lagna in your horoscope, it means saying things that you may regret later, but saying it at the spur of the moment. It indicates impulsive behaviour. On your other question the chances of arrange marriage are much indicative in your horoscope.
