When you look at the personality traits of the number 3 and the number 7, they are about as different as you can possibly get. The number 3 wants to be extremely social and always involved in some kind of activity and number 7 craves peace and solitude. If the number 7 is forced into too many social encounters, they will not function very well. Confrontation is not something that either of you want to deal with either, so you will need to learn a long-term compromise if you want this love relationship to move past the first date. To be successful in this relationship, you will need to have open dialogue about what you need and want. It may be that you go your separate ways during the day and schedule together time in order to ignite the passion.
Two numbers can always be compatible as long as you understand that there are going to be more challenges within your relationship than others. As long as you have the chemistry together, it will work out as long as you remember what your differences are and how to work them out as a couple. Much of it has to do with number 7 being solitary. As long as number 3 doesn’t mind going out with friends and leaving number 7 behind sometimes, it will be fine. The other factor is that number 7 cannot become jealous when number 3 decides to go out because if number 3 is kept cooped up, the relationship is going to become doomed. According to Numerology a 3 personality might not be very compatible with a number 7 personality.
