What stage of the relationship are you in (assuming it's a romantic relationship)? Are you married, or have been dating for years? Dating, but not that long? Or is this someone you're interested in but no real relationship exists as of right now?
If this is an established relationship, you already know what its strengths and weaknesses are. Astrology can't do much more than confirm what you already know. Does this cookbook astrology description of north node square Venus sound like what you've experienced in the relationship? If so, it's confirmed. If not, this particular interpretation doesn't apply to you.
If you barely even know this person, get to know them and have some sort of relationship with them before you start asking any astrological questions about it. Astrology isn't really useful for relationships that are only potential, not actuality.
If it's somewhere in between--you've gotten to know this person and you have some relationship but not a well established relationship--you're best off getting to know them better, rather than probing the synastry. If there are problems between you at this stage, astrology might be of some help at sorting them out... but if all you're doing is looking for potential problems in synastry when you're not seeing any in real life, that isn't helpful.
