I want out of my marriage, but we have 2 children age 5. I thought we could have 'joint custody' so we both look after them, eg have them with me for 3 days and with him 4 days a week, as they are a handful and I wanted both of us to be involved, so the other can have a break. I heard on Mumsnet that one of us needs to be a primary carer. Does anybody know how it works or throw any more light on it for me?
