Update: I am happy to report that after some heartfelt talking we have come up with what I feel is a fair solution.
I can dive once per quarter with one "Big" trip per year of over $1000.00 and the other 3 trips all under $1000.00 each.
Also, once per quarter I do something she enjoys doing and try something new such as skiing, hiking, etc.
If we happen to be on vacation at the coast and can work it out with dive buddies I also get a bonus dive in because we are already there.
