Hi again Gemsun. In the light of Kama's slightly depressing account of Mercury square Mercury cross-aspects, and to build on astrologer50s suggestion that synastry cannot make things happen, I wanted to share this quote:
'...the planet in my chart which is aspected is the way I experience the relationship. For the time being you can put aside whatever it is in your chart that is apsecting mine...Whether its a good constellation or a bad constellation is a very dubious issue because it depends very much to how I react to this thing in myself being stimulated...The actual nature of the aspect is much less relevant than whether I can relate to my own planet.'
Liz Greene The Jupiter/Saturn Conference Lectures (by Greene and Arroyo) page 29/30.
I don't see the square between your Mercurys as being a bad omen - the balance of elements in each of you means that you need one another to tune into your own Mercury's since one person's Mercury element is generally stronger in the other. If you find yourselves getting a bit wired around each other, you can find ways of burning off the nervous energy either in a joint project or separately. Most couples have areas of life where they need to create separate spaces in order to function properly (although many couples ignore this need, with sometimes rather disturbing consequences). You might possibly need to have separate learning interests, or you might not??? Like I said above, if it is an issue watch out for certain transits (eg transiting Mars, Jupiter, Saturn, Chiron, Uranus, Neptune or Pluto at the end of a fixed sign or at around 13 or 14 degrees of a cardinal sign - especially Uranus and Pluto!)
Interestingly, transiting Saturn is at 13 degrees Libra now and transiting Neptune is at the end of Aquarius, coinciding with your paying lots of attention to this aspect.
You might want to see if anything happens to do with your Mercurys on either midnight (UT) at the start of the 23rd of August, when the transiting Sun triggers the Saturn and Neptune transits, or around 2 pm (UT) on the 25th of August when transiting Mars triggers them, with a bit of help from the transiting Moon passing through at the same time.
I'd be interested to know if anything does happen....
