You are both dominated by air so this relationship can be the type where you each are creative with words in telling the other how you feel.You(in red) are dominated by fire and air. So you add passion and conviction to words and may be a lot less cerebral than your partner.
Your partner has a total of 7 placements(incl Asc) in air with a stellium in 9th.
I find stellium in 9th individuals very intelligent but impersonal. There is a tendency to look at the interpersonal relationships from a more philosophical point of view and relate on that broader notion than going towards personal feelings and emotions.
The good news is both of you are very clear in expressing yourself. The bad is that it is seldom from the heart(but from the head).
But then again neither of you are too hung up with the ambiguity of emotions. So perhaps this more cerebral approach suits you both just fine.
