A question of balance
The diagram here shows a healthy relationship. You’re S and your partner is P. Each one of you is a whole circle. The red part represents what you are, what you think, and what you do without your partner. The part in the middle corresponds to what you share in a relationship: doing things together, consulting each other about certain decisions, etc.
As you can see, in a healthy relationship, there’s a shared portion and a personal portion for each partner. Emotional dependency is when the shared portion takes up too much space. Is that true of your relationship?
