Not a guy, ignore at will.
I cry a little when he is working to revive her.
When she is drowning herself I just get pissed off, and that overrides any empathy for the characters, because they should be on their way while she is still conscious. It would reduce her total "dead time", by a lot, and a conscious woman can get out much quicker than he could get an inert body out. But drowning and final struggles would be much harder to portray on film in the open water (without actually drowning Mastrantonio).

I suggest you give it a shot. It doesn't belong in the same category as Armageddon. IMO
I know it's stupid. I thought about that the first time I watched it and I think about it every time I re-watch it, but that scene still gets me.
