You’ll never quite know where you are with a number THREE, they may not really be the partner of choice for you! They love being out and about so much, needing the stimulus of other people to catalyse ideas. Only by talking things out, usually with other people, do they gain new insights.
A number THREE are positively and absolutely at best standing in the limelight. But of course is partly what you find attractive in him. This is not so true of yourself however. You need no help sorting through your thoughts and love nothing better than to curl up with a good book and listen to music, or talk with intelligent, mature friends instead of flakes! You actually require time alone for personal study and serious intellectual thought, needing little outside social amusement.
This THREE really doesn’t have your power of concentration and unless they have a showcase or on show they are very often lost. But they do love to have dinner parties and gatherings and host them with the charm and humour only a THREE has. You may think that they drone on quite a bit and are not very choosy about the company they keep!
If you are prepared to be open minded and not too critical of their methods (which are probably so different from your own!) they can be of great help in putting your plans into action. However, physical attraction aside, there is not much to recommend this number-couple unless you have other numbers (destiny, day force, soul etc) in common. In the main, this probably won’t last very long, just enjoy it while it lasts.
