ONE and THREE are both original and strong, so there is very likely going to be some highly interesting debates and certainly an inevitable clash or two. Whoever can take the lead in this relationship will do so without asking permission. Provided you keep this top of mind you can eventually come to understand and tolerate each other well enough, though you will both have lots of vitality, so your lives should be action packed with many pursuits and activities.
If in business with a THREE there is potential to make money, as you can be encouraging towards each other with you have the same interest in mind. You are both great talkers, speechmakers and motivators and this can enable you to motivate each other into going into a pursuit or venture you may never have thought of alone.
However, it will be of utmost importance to ensure that all accounts are kept in order at all times. But whether at work or in love you will definitely have your moments where you and the THREE will compete against each other.
However there are times when you will join forces and fight off the negative energies of those who are around you, back to back. You are more aggressive than a THREE and therefore you will need to learn to co-operate if you are to live together or work as a team.
The principle problem that may arise is your need for time out, or to be alone and in your own company, or stay home. The THREE likes company, needs people around them and likes to socialise. This is a conflict that can drive a wedge in between you. And could possibly drive you crazy!
The ONE and THREE combination may work, but you will have to work on getting them to let you lead rather than follow, if you can do this then it may work out well.
