I would charitably read it as her describing her own presence in her husband's life and how exactly she's there for him. I'd take it as her talking about herself as a woman, and many people do thrive in supporting roles as opposed to leadership ones. She's every right to describe what womanhood means to her.

It might still be awkward and uncomfortable to hear (I would balk at any talk of making a company be like 'family', for example), but I wouldn't take it any further than personally disagreeing with the sentiment. No one is ever going to agree on a single definition of what family means, or what men and women are here for.
