I'm an old giffer and have worn a groove around the block.
Something I think is at play is that men often are not aware of how much work their women do in the background of their lives. I don't want to stereotype but more often than not women are oiling and facilitating mens lives but men do not actually see it.
They move out and/or 'upgrade' but find life hard because they have never actually had to clean, cook, get insurance, sort MOTs, weed, shop, creosote, stitch, polish, mend, vaccinate, clean the fridge, book a holiday, buy shoes, get in a queue, research online, get a bus, buy Nightnurse, feed the cat, buy batteries, clip the dogs claws, phone friends and relatives, buy and wrap Christmas presents, pay the TV license, sniff gone off milk, iron clothes, wallpaper, pay the bills on time, check the bank statements, pay the cards off. As infinitum.
It's like they think the fucking fairys did it all!
Sadly I think this is often what drives them back home. It's dressed up as love but actually I think it's the fear of a second dose E coli
