Ok. I'll give you a quick summary of my thoughts. 1. You have a lot of nice synastry aspects between you:
A. His Venus trine your mars/sun conjunction. This will help make you feel lighter and more affectionate in his presence. You probably have a strong drive, no? His energy from his Venus would help to soften that in a sense.
B. His mars trine your Pluto. This is a really nice, erotic connection between you. You help to bring out the deeper side of his sexuality, and he does this for you as well.
C. Your sun trine his moon. This is referred to as a classic compatibility aspect. Your presence triggers his more emotional responses.
D. His Saturn is unaspected based on the chart you posted. This may reflect in a resistance to commit, or voice his commitment to the relationship perhaps? However, this planet falls in your 7th house, which may offset that. Regardless, his Saturn here might stir your desire to have him fully committed to you, such as in a marriage.
E. Your Venus is on his north node. He would want to open up his affections towards you. He feels cared for with this touching his north node.
F. His moon widely conjuncts your north node. He wants to protect you and give you emotional security.
However, in his natal, it appears he has a wide opposition with venus/uranus. He likes to exert his freedom. He likes his own space sometimes in a love relationship.
It appears you are deeply involved in this relationship at an emotional level. Looking at a comparison of your natal chart to the composite, your descendant with Pluto sitting right there, is conjunct the composite moon. This should signify that the relationship resonates at a deep level with you.
His natal ascendant is lining up with the composite sun. He should feel very connected to the presence of this relationship in his life.
What specifically are you feeling in this relationship right now? Is he relaying that he's restless, bit still pulled towards you at specific times?
Again, just a quick summary, but those items stood out to me.
