I sometimes make jokey comments about him being ok to keep smoking or such "because he's insured, so it's ok".
Or that "I'm really annoyed by him but I can't leave because I'd get no life insurance payout so he'll have to just die instead".
My husband is the absolute love of my life. I wish him no pain or suffering. But every once in a while I have fleeting thoughts of what my life might be like if he died...
