I am still very much an ameteur, but when I saw the relationship between Venus, Mars, and Saturn my first instinct was that Mars is the barrier to this man and his wife coming together and being happy by trine. She is Mars, so she represents an obstacle for this couple. So my instinct was that she should remove herself completely from the situation, remove all tempation for Venus, and allow them to work it out towards the positive outcome together (shown by their trine) that would happen if she wasn't there. It looks to me that Mars is trying to tempt Venus and throw him off track.
