I wasn't sure where to post this so I settled on this section.
I will start by saying I've never been to England (we're going for a visit in January and moving in July next year) so my impressions have been formed only by interacting with my MIL, SIL and a few Brit friends on other pregnancy/parenting forums.
MIL has been a SAHM basically her whole life, my FIL has never cooked a meal and doesn't even do the traditional "male" jobs such as mowing the lawn. MIL doesn't complain whatsoever and seems to like the situation because she is so "needed". Her kids are grown and she still babies them immensely. She doesn't have a career, job, or any hobbies aside from domestic things.
During a rough period where DF and I were arguing a lot about the impending move my MIL called and we had a lot of no-holds-barred conversations.
Her opinion: I'm silly for even questioning whether the move to England is a smart one. Why? Because a woman must follow her husband. She had to do it, my SIL did it, therefore I should basically shaddup and stop making his life harder by being realistic (or negative, impossible, etc in her eyes).
She's told me that in England women don't feel pressure to go back to work with young kids. It's just so lovely, you cook, watch telly and pick up the kiddies from school. Only cold hearted career driven women, or women of poor families go back to work before their kids are in school.

This scenario has been cemented in my mind by watching too much Wife Swap UK, and tidbits from online friends (ex "I'm going away for two weeks and my husband, bless, has to learn how to use the dishwasher!" or "I was ill with pneumonia and my lovely husband LET me have a nap while he played with the kids!").
I'm not convinced that this is a UK thing. I've just been unlucky that I've never met a woman in the UK who is not a SAHM.
So, for those of you already there or with any experience beyond mine, how are gender roles in the UK? Is it a bit backwards? The same as the US/Canada? Will I be the odd woman out if I return to work just because I desire to?
