Hi,
To add to AppLeo's good delineation, Venus is not only in Sag, but also in conjunction to a strong Sag. Jupiter. Venus is also sextile Merc. and this could mean that the spouse might be rather communicative and well-read. This aspect and the fact that Venus is in Sag. and conj. Jup. could mean the relationship might involve some travelling, at least in the beginning.
Venus in Sag. and aspecting Mars in the 9th and almost in the tenth could show that the person might in some way be connected to law/ govt. or have a career that involves overseas travel.
Keep us posted about your next relationship.
