I think that it's more likely that you will ask for his.
You're the Sun in Aquarius in the 7th, in the house that rules him. However he makes no aspect to you. Saturn receives the Sun, but there's no relationship between the two signs. This suggests to me that it will come about through your striving rather than through anything on his part.
The Moon in aversion from the Ascendant is also a testimony that he won't.
He is in a cadent sign that is in averison from the Ascendant. That's another testimony that he won't act.
Your significator is however in an angular house and hovering around the Descendant. You're more active in this chart than he is.
So you may get his number, but it seems like it will only be through effort on your part. Since Saturn is involved here, I don't think there's anything romantic going on. The Sun's next aspect is to Mercury, ruler of the 11th. This could mean a few different things. You might end up just becoming friends with him (considering the above, likely) or more specifically you might end up asking him for his number in a group setting, a business setting because of Mercury.
Good luck!
