BYZ,
In this case the Moon is important, as while it is in Aquarius, the degree cannot be determined accurately, and there is a good possibility that Uranus will be conjuncting the Moon sometime within the next year - and that will make him very very unpredictable.
Without the time, looking at his personality is really not possible...
As for the synastry, there is not much there - a semi-square between Venus and Pluto, which would indicate that the two of you have known each other in a previous life, but that is all there is - no real Saturn contacts nor any real inner planet chemistry. In other words, your instincts were right.
Right now, there is not much going on in your chart either positively or negatively for romance, so it is up to you. Now, in 2001 and 2002 Pluto will be squaring your descendant and conjuncting your Moon, so at that point you will be undergoing some major changes in how you feel and look at relationships...
