I think it should be important to consider the grand earth trine in both the composite and Andy's chart. This might create a more "easy" grounded energy between those planets not suggested by the difficult aspects.
It's interesting because you were born close together, where his sun forms a grand trine but yours does not, but in the composite it is there. The relationship might be giving you that grand trine easiness that is suggested in your chart but not quite in aspect. Since it involves the Sun, it's important in my view.
There is a lot of Virgo energy, and I feel like Uranus in Virgo, especially within a grand trine, is not going to be as difficult to assimilate as you'd expect. Uranus in Virgo with lots of trines makes me think of bucking the status quo by NOT bucking the status quo! Following the rules is more "shocking" than not following them. Being the rebel by not being rebellious. I'm furthering this conclusion by the square to Saggy Mercury and Venus, which loves freedom and integrity, with the ruler (Jupiter) also part of this grand trine in Taurus, the sign of personal values and material wealth. The opposition with Moon/Neptune shows how this might conflict with the "secrets" that you keep between the two of you.
I'm picturing this relationship as looking like it's playing by the rules, and finding it easy to keep up those appearances, have the house the white picket fence or what have you... but secretly there is much more going on, your wildest fantasies and dreams between you of how you'd like to live your lives (even together) would not be acceptable in the public eye, or would be considered unusual or outlandish, overly idealistic, etc. Living like nomads, for instance. But you are ok with dreaming about it rather than living it, and might be compromising that way. If there is a conflict, it may be here, where one of you is happy to keep playing to traditional couple role and the other isn't, or you try to live that fantasy and it becomes destructive, or something similar. But it isn't necessarily a problem, but may actually get you closer to whatever life you'd like to have. Someone to share your crazy dreams with is not so bad!
Just gonna say... 10 months isn't that long!
Err.. at least that's my first guess. Hot or cold?
