People tend to go overboard on some subjects, and it sounds like your wife has been reading too much feminist propaganda. The goal should be equality, but not a denial of the differences between men and women. Find a counselor, preferably female so that your wife will be more comfortable, and get some help. If your wife won't go, go alone. The counselor will give you information on how to cope with the situation. A trip to an MD to see about treatment for the snoring would also be a good idea.
