I am a full time working mum and my DH is a SAHD. Our relationship is in tatters and I think we need to split up but I am really worried about my rights. My kids are still very young ( 3 under 6) and my DH is not from the UK. I am terrified he will fight for custody and take them abroad as he doesn't have anything to keep him here. Although I work, I spend every waking moment I can with them and take over the child care the minute I get home. Am I right to be worried?
