Hi ^_^ Theoretically, just based on these aspects, I'd say that you would have a strong influence on him.- your Sun on his Vertex, you might have a deep impact on his development, and this kind of impact (Vertex impact) does feel fated.
- your Sun conj. his Chiron - you might touch his pain, he might be vulnerable to you.
- your North Node conj. his Chiron - it might be in your path that you'd encounter his pain.
- your Ascending conj. his North Node - this can be a very binding aspect, and basically, you might have a big influence on his life lessons.
(the above aspects should be tight to feel the effects thought)
But well, these are all just based on astrological theories, and just based on these aspects alone and not the rest of the synastry aspects or other astrological factors.
But what's important is, despite the astrological aspects, how you really feel in the real life.
