I wouldn't. I wouldn't even tell my DH because he is the breadwinner, I am a SAHM with no money other than my DH's.
I would love to put money away just incase we ever split so that me and the kids wouldn't end up penniless, especially as they have become accustomed to a nice lifestyle.
I wouldn't even tell my parents.
Would you tell anyone? Do you think I am being mean not to tell anyone?
