I'm beginning to think that diving with one's spouse is simply a recipe for trouble.
..snip..
Well since this old thread has been reactivated I'll add a new comment about a recent incident I had.
My wife was always my favourite buddy but as is often natural our comfort levels started to diverge and matters came to a head when we were doing a night dive in a cavern with about 10 other divers and 7 large agitated turtles. absolute chaos. Without really thinking I complained about her finning raising silt - something she doesn't normally do and we got into an argument. Anyway I only realised that she was totally stressed out when I looked at her SPG so I grabbed her and got her out of there fast - which basically meant setting a compass heading for the entrance as by then there were clouds of silt with zero vis everywhere raised by several of the divers some of whom were actually rolling around on the floor. There are other lessons here but they're off topic and not relevant to the point I want to make.
Anyway after we got back to the boat and both calmed down we had a long chat and the main lessons were:
1. If you're diving as a buddy pair then the dive should be within the comfort zone and capability level of BOTH divers.
2. If either member of the buddy pair is not at ease with the buddy arrangements, then change them - before the dive. Once you start the dive your commitment is to support your buddy.
3. Neither buddy will pressure the other to go beyond their comfort level.
4. Neither buddy will complain or make the other feel guilty about suggesting a buddy swap for a specific dive.
Prior to this incident we had only dove with each other for around 200 sequential dives, since then I have done some with other buddies, but the great majority are still with her.
Nowadays I actually enjoy more my dives with my wife because I accept them for what they are and the little bit of subconscious frustration that was probably at the back of my mind has gone away.
For me this incident was a valuable lesson which really made me rethink my attitude - fortunately nobody was hurt by it.
