A TV interview I saw with a couple the better part of 20 years ago burnt an understanding of this into my mind. Husband was a real man's man - been a miner and he lost his job when the pit shut. Wife became the main breadwinner, and she basically said that she lost respect for him and stopped putting out. I doubt their marriage lasted, which was sad given they had 3 or 4 kids iirc.
It doesn't have to be as huge as becoming a house husband; even having a hiccup in your career or being temporarily unemployed is enough for a lot of women to lose respect. In my younger days, I had a couple of hiccups in my career before getting back on track and each time the woman went as well as the job. You could see the cogs turning. Both times the set back turned out to be a precursor to a leap forward. Both times, once "success" was back on the table, the women concerned started "showing regret" and came sniffing around again. Both of them were alleged "feminists." The strange thing is that I don't think they quite understood themselves why their feelings had changed. It makes one dreadfully cynical, and much more careful/choosy. Thank god I didn't have kids or significant assets at the time.
The courts don't seem to treat house husbands who are dumped after giving up their careers in the same manner as house wives. The setbacks and loss of future earnings in this ageist world are almost as bad for men as for women. It is a real injustice and makes an absolute mockery of the lip service paid to equality.
Ive had this situation once. What got me about it more than anything is that are women so short sighted that they don't know you're going to get back on your feet sharpish and won't rest until you're at least back to where you were before? I used my redundancy to change career and, in the three years since, am now doing better than I would have been in my career with better prospects, this after learning that some careers pay better than others for no reason other than supply and demand of candidates.
