People with low levels of emotional maturity or differentiation attract other people with low maturity levels, and people with higher levels attract higher level people. Theoretically, in order for people to attract each other in the first place, they must be at exactly the same level of differentiation. That being the case, it is impossible to attach blame for relationship problems to one or the other partner. It is productive to look only at one’s own contribution to the emotional challenges of the relationship.
