Aries and Aquarius
Just like you, Aquarius doesn't think a marriage is based on the merging of personalities, but rather on the union between two different entities, so Aquarius will not suffocate your spirit. But Aquarius is much more flexible than Aries, so pay attention: if something seems vitally important to him/her, (s)he won't give in, (s)he will be very firm about it.
Sexually, Aquarius (the sign of inventiveness) and Aries (the pure energy) will make a perfect match. Your Aquarius will be different every day and you like that, because it satisfies Aries' thirst for adventure and novelty.
The beginning is a little difficult with an Aquarius, who is very friendly and charming in the society, but who opens up slowly in personal relationships. But I doubt that this will be an obstacle for a real Aries, that is an impetuous sign.
Fortunately, neither of you is possessive. When you want somebody, let him/her free: if (s)he doesn't come back, it means (s)he was never yours. Sometimes you may find it hard to follow all the Aquarius's changes, as it would be difficult to follow the change of wind: we feel it, but we can't say when it started and passed by, where it is headed and where it comes from. You will often think that (s)he gets lost on the verge of the unpredictable, but, after all, that's what attracted you from the beginning, isn't it?
A fairy-tale relationship: Aries and Aquarius need each other and can support each other like Air and Fire.
