I would just suggest that you question as well as provide information. So, you can ask the question and be as detailed as you want, but as a side note you can provide other details in case there's something going on. In a general way, having no Planets in your 7th IN KNOW WAY in and by itself influences in a big way. You can read stuff on "Empty Houses" such as :::
"House types correspond to qualities and are given special names: Angular, Succedent, and Cadent.
Angular houses correspond to the Cardinal signs. These are houses 1, 4, 7, and 10, the houses that begin with the Angles of the horoscope.
Why are they called angles? Centuries ago, astrologers didnt draw horoscope wheels. They made a square with the sharp corners going left and right, top and bottom. Of course, the Ascendant, Mid-Heaven, Descendant, and Nadir landed on these angles. The name stuck even after square wheels went out of fashion.
When anything is missing in a chart, there are always two ways to deal with it. You can totally ignore whatever is missing. It doesnt concern you. What you dont have, you dont miss. Or, you are very aware of what is missing. It is a lack that you can spend your entire life trying to deal with. You can overcompensate and turn the weakness into a strength. On the other hand, it can overwhelm you.
Missing Angular Houses: When there are no planets in Angular houses, it becomes more difficult to initiate things, to stay in the here and now. An example of overcompensation would be Raquel Welch. One of the hardest working people in show business, she had no trouble diving in and getting the job done. Seven planets in Earth signs makes her concerned with material resources and their accumulation, as good an incentive as any to keep working (especially since four of them are in Virgo, sign of work).
Missing Succedent Houses: When there are no planets in Succedent houses, the result houses, there is could be little (if any) ability to focus on ultimate or long range results. Or there may merely be no concern with these things at all. If you have this one, it doesnt mean that what you do wont have any lasting effects. It just means that this is not your focus. Jennifer Jason Leigh has no succedent planets. She has seven in cadent houses, which increases her ability to develop characters (cadent houses deal with background) but there is little, if any, attention given to whats down the road.
Missing Cadent Houses: When the Cadent houses are empty, there may be no sense of your background, of what has gone on before, and that could mean you can find yourself always starting over again from square one. Or you could be unconcerned with background matters and simply take them for granted. Elizabeth Taylor would be the first type. Anyone who gets married eight times simply isnt learning from experience. Prince Charles would be the second type. Hey, hes the Prince of Wales. Most of the ceremonial duties and responsibilities fall on his mother, the Queen. He can do what he wants."

That Web site is frequently recommended for "beginners" to get an overall brief lesson on the basics. Very easy to read too.
But to answer you, the Sign your DC is in is probably not capable of making an Aquarius chase you. You probably have some wicked Aspects having to do with Aquarius/Uranus/11 House, either in your respective Natal's or Synastry or Composite.
Your 7th House Cusp is in Aquarius, which is also known as DC or Descendant. This is Opposite of the Ascendant and frequently associated with the "type" of person you are attract to/attract. It usually doesn't mean that this is specific to Aquarians. Rather, it's a TYPE. So what might do it for you might be something as simple as the dude having his Uranus in his 11th House, if that's what kind of energy you seem to be connecting with at the present time.
I have my South Node in Aquarius. South Node can feel very similar to the Descendant in terms of what effects you might notice. But they offer distinctive insights. Both provide a reminder to us of a previous incarnation.
