Re: A friend at work
Actually that was a pretty good piece of marital advice - spice it up a bit! Seriously though, it sounds like this couple hasn't been married long if they haven't figured out how to share the shower.
Is the husband going through some other tensions with regards to money, work pressures, his family, etc.? My husband will occasionally vent at me when he is upset by other issues, because he considers me a "safe" target (i.e. I'm not over the top dramatic like his mom or sisters, and I don't take it personally). That said, she needs to clearly define what is and is not acceptable - i.e. it's ok to have a go at her once and awhile, but no swearing.
The fact that he mentioned her job makes me wonder if the husband is feeling some financial pressure from somewhere. Is he supporting his parents and siblings, or do they depend on her job to help pay the bills? If I were her, I would be loving as usual tonight, but let him know without harping or moaning that its not acceptable to scream at her.
