The questioner, a woman, asked : "Is my husband happy in our marriage, does he truly love me, or does he wish he was somewhere else. Does he fantasize about other women?". No other info available.
This question was received on April 29, 2005, at 3:52:40 pm EEDT, in Tirgu Mures, Romania (24e33, 46n33).
Chart significators: Mercury rules the 1st house and represents the woman asking the question, Jupiter and Neptune rule the 7th house and represent the husband.
We see the two main significators separating from an opposition, also the Moon separates from two squares with both Mercury and Jupiter, clearly indicating the relationship to be cooling off after a conflictual situation.
There is no mutual reception between the significators, not even a reception, so the two spouses seem to be live in separate worlds.
However, there are a few elements that might keep this relationship for a while: the Moon and Venus (natural ruler of marriage) both in positive aspect with the ASC-DSC axis, the Moon applying to a first aspect to Venus, Jupiter retrograding in the 1st house, indicating efforts to make it work.
The next aspect of the Moon is the opposition with Saturn, announcing more difficulties and coldness in this relationship. And the last aspect is a trine with Fortuna at 26° Taurus, but this one is in conjunction with Algol, most malefic fixed star of all, which deprives the Part of Fortune of its beneficity. Another noteworthy element is that the 7th house cusp is in conjunction by antiscia with the fixed star Vindemiatrix (10°01' Libra), which is traditionally associated with falsity, dishonesty and widowhood. The antiscia is however a subtle cosmic relationship and it shouldn't be taken literally, this is just an extra element that adds more weight to the above analysis.
The last part of the question was is the husband fantasize about other women. We see Neptune (modern 7th house ruler) in square with Venus and this is so typical for fantasies, so it confirms the querent's suppositions. Also, Jupiter's (traditional 7th house ruler) mutual reception with Venus by term, supports this theory. Even more, as Venus rules and is located in the turned 3rd house from the 7th, the other woman may be a neighbour or a cousin.
