Grand trines in synastry

[Astrodawn]

I would appreciate your thoughts on some of the chart aspects between myself and my partner.
I have never felt so open and at peace with anyone as I do with him, we both agree that we have found a pure love and I really believe that we have. After a life full of poor relationships (my saturn in 7th house) I think I have found my life companion. Together we are sort of enveloped in a warm world of comfort of our own, and he says that my hands heal him everywhere they touch him? I would have thought this to do with chiron but I cant see an aspects (although I am no expert)
I am interested in some of the synastry aspects especially the ones forming grand trines, is it these that are causing the intense feelings of comfort and companionship?
his ASC (5 leo) his VENUS (5 aries) my VENUS (5 sag)
my ASC (21 leo) my MERCURY (20 sag) his SUN (22 aries)
also theres an interesting conjunction to :
my MC (4 taurus) his jupiter (4 taurus) his mercury (4 taurus)
my IC (4 scorpio) my sun/moon midpoint (4 scorpio) his uranus (4 scorpio)
I would appreciate anything you have to offer on the chart its got too complicated for me :) I would to know that these feelings are going to last.

i ran a composite up for this relationship and it does show many endearing aspects.
the moon is trine to sarturn indicating a steady ,harmonious connection.the venus/mars midpoint is opposed to jupiter indicating a optimistic and loving connection with a steady longterm potential.the moon/mars midpoint is opposed to the mercury/sun conjunction showing very good communication and expression of emotions.it actually can give a "psychic" connection where you thoughts occur in unison.with mars on the ascendant,the relationship energizes all aspects of your lives.it gives a robust and otimistic appraocjh to the world in general.
mars is square to saturn which indicates that it is not all roses,this shows that committment with come gradually and there will be some difference to iron out.this would indciate he is a bit more hesistant to committ that you are.
one aspect that is suspect is the neptune square to the sun/mercury conjunction and the moon/mars midpoint.this can indicate hidden,unspoken emotional issues.it can indicate overt deception.it can also be a function of difficulties in view points because of the age difference.as there is good ,this shows that there is still some retience.
