I used to say to my DH that I wanted a divorce so I’d have EOW free! 
When it’s hard, when they’re upset or sick and I’m worried out of my mind I do think how much easier it would be. But I think that’s an anxiety I have around them and something I’ve realised I need to address.
Then of course the usual - the mess, the bickering, the finances, the monotony especially in lockdown....
