Back2Two, this is how women get slapped down all the time.
Discussing the division of labour is trivial.
Wanting equality and respect in your relationship is trivial.
We should all be worrying about much bigger, more important issues.
You contradict yourself by acknowledging that perhaps some roles have been internalised, but that somehow that's not a feminist issue, it's just a discussion to be had between two people. If roles are so powerful that they can be internalised by intelligent, aware people who are doing their best not to internalise them, how can that not be an issue worthy of discussion?
Millions of couples have this discussion every day. Unfortunately for many of them, the internalisation of the roles is so strong, the slapping down is so crushing and the guilt for getting upset about something everyone is telling them is so trivial is so strong, that it effectively shuts women up about this.
And the upshot is, that the love and trust and respect many women have for their partners, is corroded and damaged because of a low-lying, simmering long-term resentment which they feel guilty for having (because wanting to be equal is so trivial) and can actually long-term damage a relationship.
And that is really, really sad. Because a lot of decent men who aren't aware of their privilege, find out far too late, that all those trivial little things that they deemed not worth discussing, have led to that gulf which means that when the children grow up, the couple find the friendship they once had, isn't there. They hadn't noticed, because the bustle of everyday life covers it.
The happiest couples I know, are the ones where the parties are real friends. You can't keep a friendship long term, if your friend is either exploiting you or you are exploiting them.
This isn't just a feminist issue, it's a real relationship one. Because it's deemed as too trivial to discuss, I'd hazard a guess that it probably causes as much trouble to relationships, as money or sex.
Luckily it looks as though the OP is married to a decent cove who wants to sort this out. So he doesn't think it's trivial either.
