According to my software your husband is still in the major-period of the Moon till 09/January/2023. He will enter Mars major-period from that date.
The Moon is the owner of the ninth house and should therefore have given good results since the time its major-period started on 09/01/2013. It is debilitated in the ascendant, dark, placed in Jyestha nakshatra of Mercury and is associated with Jupiter so the quantum of good that Moon should have given must have been limited, interspersed with occasional unhappiness relating to employment matters. There might also have been obstructions in life and career, and no faith in religious and spiritual matters in this major-period. Moon has not been able to give what it should have on account of its ownership and placement. Currently the sub-period of Venus in the major-period of the Moon is operating. It started on 8/November/2020 and continues till 10/July/2022 when it gives way to the sub-period of the Sun.
Venus rules the seventh house of marriage and relationships. Mars has joined it. Mars owns the twelfth house from the seventh which means that there may be times when he may be separated from his wife. Since Venus is strong in the chart there may not be any lasting impact on marriage. His efforts may misfire and he may not find success. Saturn being debilitated gets into close relationship with Mars. There could be property disputes, alienation of property or change of residence.
