It's sweet that he "treasures" them so well. But I can understand your frustration, too.
I'm grateful I learned to quilt with Mary Ellen Hopkins who wrote "It's Okay if You Sit on My Quilt (Because I Can Make Another)" because her philosophy has colored my perception of the life and strength in my work and the quilts.
Perhaps you yourself might take one out and drape it across the back of the sofa "for winter use" or display. See if he actually fights you over that.
Otherwise, I guess you could ask him if he is saving them for his *next* wife!
