Hi. You seem go have similar charts, both with a Leo emphasis, and he has the very wilful looking ascendant while you have the Sun Mars Saturn configuration. In your chart Chiron forms a very tight configuration with Sun and Mars, and as far as I can see that is the main say that Chiron features in your chart. He has the Moon Chiron conjunction, suggesting that Chiron themes will be emphasised in his experience of you, and also that he may provoke you to express such themes by virtue of his expectation of this. The same could be said of his Moon in Pisces, even though Pisces and Neptune don't seem to figure that strongly in your chart.
So one thing you can do to ensure that you oblige his expectation of Chironian mothering in a positive and conscious way is to look at how you express Chiron, which can be aided by looking at the Chiron Sun Mars configuration in you birth chart. Things to look out for include a sense of being victimised or helpless, and a sense of unfairness or resentment, around the expression of your Cancer Sun and Capricorn Mars.
You have Chiron plugged straight into a very wilful part of your chart, where as he has Chiron in a very unwilful conjunction with the Moon in Pisces, somewhat disconnected from the wilful Leo and Scorpio placements. This may be significant in some way. Perhaps the Chiron theme and the wilfulness have to be separated out from one another more starkly in the next generation of this particular lineage. In any case, he may be especially attuned to your Chiron, picking up on any despondency and sense of being wounded, and also on your compassion and urge to heal.
The way that you respond to his expression of will may be very telling, perhaps illuminating wounds that have been largely unconscious. You may feel guilt around meeting his will with your own, for example. Rather than issues of abuse, I would watch for this kind of dynamic, which, in extreme cases, is a form of self-abuse anyway.
But time will tell. I would try to ease off on the astrology with regard to being a parent. Cancer and Capricorn are concerned with trying to establish a secure foundation from which to move forward. Saturn makes tense aspects to Sun and Mars, and Chiron brings a sense that the rug will be pulled from under one's feet because people can be cruel and life can be unfair. Mercury square Pluto adds to the compulsion to analyse. So you may get lost in an unfounded sense of urgency with regard to acquiring knowledge which will make things more likely to work out.
I don't know if this will have any resonance or practical use, but there it is.
