~first~ and ~second~, it is uncommon for these two numbers to "fall in love." Although they carry common traits (they are both practical and highly responsible) they are rarely interested in one another. The 4 and the 6 are both family-oriented numbers, with a strong sense of community and loyalty to others, but they tend to compete where you might expect them to be supportive. This is only one area of your chart, so there are other influences to consider that could mitigate this competitive aspect, but it will quite possibly be the hardest to overcome at the onset of your relationship. 

However, if support prevails over competition and you do become involved in a romantic relationship, it will usually be a strong, comfortable alliance - the kind of relationship others view as indestructible. If you can accept your differences, you have the potential to be the "perfect couple". 

You share important priorities: your home, children, friends, stability, and security. You are both loyal and protective of each other and those you care about. It is in your approach to life and the way you express yourselves that you are quite different. While ~first~ (the 4) relies on structure, discipline, and control to protect and care for others, ~second~ relies on warmth, sacrifice, and forgiveness. ~first~ is much less flexible and may, at times, feel that ~second~ is too soft and lenient. Yours is an example of a relationship typically characterized by the disciplinary father and the soft mother, or vice versa.

People around you may have the impression that ~first~ is rigid and less loving, while ~second~ is pure love and gentleness, however this is not an accurate perception. ~first~'s love is no less powerful than ~second~'s - it is just less openly expressed. ~first~ will fight for, and sacrifice, just about anything to protect ~second~, the children, and anyone else who is part of their life.

Some danger exists if your differing attributes become too magnified. ~first~'s need for discipline and structure could become too much for ~second~, suffocating and limiting their ability to express love naturally and without anxiety. ~second~'s willingness to be generous to a fault (and possibly be taken advantage of as a result) might lead ~first~ to lose respect for them.

Your loving natures can help you weather such conflicts and differences. Stay focused on your love, commitment, and shared values. If you can talk openly about your issues, and respect each other's individuality, you have the potential to maintain a strong lifelong relationship.
