So long story short been together for 10 years. two kids one 9 years and other 10 months old. I don't want to be with him anymore and I know I'm going to have quite a fight on my hands and the aguements anyhoos I'm thinking I should save up some money before hand as he's the one who earns all the money (I'm a stay at home mum). How much should I save? And how to keep my courage to do it?
