I totally believe in the whats mine is yours statement in a marriage ...
However , me personally ...I know DH will be inheriting quite a bit from his grands and his parents .... to me thats all his .... to do what he wishes .... now if we were in financial crisis obviously I would expect him to do whats
necessary for the family , but as long as we are both employed and paying the bills on time I would not want anything to do with his inheritance ...and would back him up in whatever he decided to do with it ....
Look at it this way - He didn't take off on a trip with the guys , or go out and buy a motorcycle ... he put it in a savings .... which IMO is actually a very good place for it ...KWIM?
I understand what your feeling ...but to me it is his personal legacy from family
