Two people are good company because they meet each other’s emotional needs.
If someone doesn’t meet my needs emotionally, they are not good company and I wouldn’t spend my time with them.
Three’s a crowd means that I am not getting my emotional needs met by either of the other two. I may as well be in a crowd, for all the benefit that I am getting emotionally.
In a crowd, I lose my space and I drain my energy when my emotional needs are not being met.
Two alike people who like each other will develop a co-dependent relationship.
A co-dependent relationship is one which meets the emotional needs of both partners and allows them to relate together well.
A co-dependent relationship between three people is a very rare development.
It is an ‘eternal triangle’ that requires all three people to meet each others emotional needs equally, fairly and consistently.
When all emotional needs are met, the threesome is no longer a crowd, it has become a ‘team’.
