H ( dropped th DH sometime ago ) and I separated in November and all has been quite amicable. Relationship was over years before and really we have just been going through the motions for a long time now, I suppose for the DC's. But I realised in Nov that I wasn't prepared to sacrifice having a loving and intimate relationship with someone and was far too young to settle for the life we had- basically he lives a selfish single bloke lifestyle with no responsibilities whilst i function like a single parent anyway. I now realise that I must cut all ties financially and can just afford to pay the mortgage, bills etc on my own. BUT, what am I entitled to ask him to contribute towards ? I know he should pay 20% of his net salary in child maintenance, however he is self employed and takes a salary via dividends so ultimately I could end up with nothing from him if he choses not to declare his take home pay. BUT and again it's a big one this time, if it does stay amicable should he be contributing to anything else ? From my calculations I'm likely to be left with about £60 a week to feed, clothe and run the car etc for the three of us and the dog, while he will have around £400, doesn't seem entirely fair. Thanks in advance for any advice
