text: does a diffrence of 9 years make diffrence in husband and wife relation ? my sis will be marriang a doc who is 9 years older than her, so she is scared about wavelenths and other thigs does it really make a  diffrence, what type of adjustments she has to make..? depends on your sister.  she will probably be well taken care of and a lot of women would prefer that over any deep relationship.  women do want "security" to feel comfortable in a relationship.  the guy has been in school for a whole 8 years longer than most people so he is probably emotionally 8 to 10 years younger anyway.    he gets a trophy wife and she gets the much sought after "security".
