There are plenty of ways to make money that don’t involve going to an office everyday, and that people who do invalidate as not working. Not everyone’s life looks like yours.
There are plenty of ways to have a relationship that don’t look like your household. That’s OK. It’s not a criticism of your lifestyle if that works for you. It’s not ‘unfair’. You live in the same system and could make the same choices.
Even if they are on benefits and living apart to be better off, they didn’t make the rules. And the rules are the same for everyone. Why shouldn’t they have the living arrangements that work best for them if it’s within the rules. How many people don’t need child benefit to feed their children, but still claim it and spend it on funsies? It’s morally no different, you’re just haggling over price.
If they lived together, he would be financially better off, have more space, more financial control, more power, do less work and still be able to easily waltz off any time. There is little benefit in living with a man and very significant risks and penalties. I think we should be promoting systems and venerating women who force men to cede control in families. They’ve had long enough to do it voluntarily and they don’t.
