OP - Yes, although I know that my work is considered secondary to his.
Not particularly by him (although he has his moments), but by the world in general. My work is part time, pays 1/10 (pro-rata) of what his does, his salary pays for everything, his is a 'career', mine is a stop-gap. He is away a lot with work and has lots of non-office hours work-stuff phone calls etc, mine is strictly 22.5 hours. On the plus-side he does work from home when one of the kids is ill or we need childcare cover.
That said, I do know that he has moments of feeling a bit like a spare part when he gets back from time away and the house/family is ticking along nicely.
Aside from the massive salary gap between us, I do feel that we are equal. All decisions concerning the family, finances or otherwise are jointly and I feel that my opinion is just as valued as his.
