I'm tired, fed up and always damn hungry! I don't know what to do maybe I'm foolish for thinking he will change and realize what he has. I have two kids and still run my business with the kids there. Deal with customers their orders and still come home and cook and clean and wash. While he works a swing shift. How do I tell him that I want to separate so time will tell if it's gonna work or not. Funny thing is I can handle all the work I just can't stand him not doing anything with himself no aspirations or goals. We still live with my parents and after 3 years of being married can't find a place to live in?
