I'm thinking of dividing my income between "money for me", and "money for the family"
Is there a reason why you're thinking about your finances?
The purpose is to have a little more money for me and cause less financial stress to my family.
It's nice of you to share money with your family. They will appreciate it and look out for you if needed.
I've been doing this for about a year now.
It seems like you are very financially responsible. Good for you.
