In Rasi Chart, Moon is in Parivarthana with Mars, and in Moon dasa the results of Mars are shown.Mars is the 9th house lord (dharma and the seed house for Navamsa-D9).Mars aspects by Graha dristhi the 7th house and the 7th house lord, Saturn.The 7th house shows marriage/relationships.
In Navamsa, Moon is with Mars and Saturn.If we place in the order of maleficience we have Saturn, Mars and Moon.So, Moon will give the result of Saturn, and Saturn will give the results of Moon.Mars will give his own results.Saturn is in Lagna in Navamsa (a new beginning in the matter of Navamsa, so marriage/relationship), is the lord of a kama trikona house (3rd house- the seed for the kama trikona houses-3rd, 7th and 11th), and aspects the 7th house and the lord of Navamsa Lagna, Jupiter.
