Nodal contact is a generational relationship and connection aspect.
It will be felt more strongly during Eclipse seasons more so every 19 years (Nodal return) and halfway in the cycle every 9 years.
By synastry, it does contact your Mercury/Jupiter in Aries square his Mercury/Mars in Cancer.
This aspect in your chart shows that you are a self-learned person in your belief system not following the popular trends, always seeking to expand your independence and knowledge. The trine to Saturn/Uranus in Sagittarius represents the urge to break free from all the limits, rules and restrictions imposed by Saturn (dictates of society).
His Mercury/Mars in Cancer squaring your Mercury/Jupiter/Node shows that he will challenge you on this aspect of your personality forcing you to take a stand on your religious, spiritual, education or philosophical views.
A very interesting aspect if you like to have 'hot-stove' discussions!
Blessings!
