I'll post more later but one thing she gave me examples about relationships using anonymous clients situations was this:
Same Values, Same Maturity level, equals 'real mature love'.
My STBX and I have different values when it comes to commitment. We are 10 years apart in age, and she is not mature.
Counselor said that she has worked with couples who have weathered cancer, accidents, deaths and much worse. Yet, because they had the same values and maturity their marriage survived.
