Have been in the same boat with respect to the non diving wife,, Our solution was an easy one found dive buddies who also had a spouse that didn’t dive, planned trips together that afforded the "NON DIVERS" things to do and see, while we hit the water... And as stated above you have to make some time to do the land lubbers stuff with them to keep the peace.
It is a very delicate balancing act to say the least but if you truely want it to work out then it will with some give and take on both parties..
Live aboards are a great way to get the best of both worlds, spend some time do a little research and most of all talk to her and explain what you would like to get out of a vacation, and be sure to ask what she would like to have from the same vacation...
There are a lot of non diving spouses out there, for me I have decided since my divorice many years ago I will not date or Marry a non diver..
Good luck.
