Spook - X2b ignored and did not fill in his financial forms properly - get your soliciotr to apply for a court date and to put in a request for ancillary relief as well as putting a time limit with a penal notice attached for him to reply to letters etc...
It really works after 2 years we are finally going to court very soon.
As for the settlement - tell him that neither of you can discuss it until you have had your Financial Directions Hearing to see what a judge would award you so thet neither of you are going to be able to get on or make decisions until he fills the forms in.
Do not start selling portfolios etc. if he has paid the mortgage always and he stops now it will make him look like an arsehole in court - by all means put money into an account but a bare minimum and contact the CSA to get them on his case ASAP - with the threat of ancillary relief, child support and court believe me he will realise that the longer he leaves it the more his pot will depleat and it is in his best interest to get this all sorted out quickly!!
As forseeing the boys that can also be set in stone by the solicitor - it would be every other weekend and half of the school holidays usually if set out in court and tell him you are not going to do this but in the end will have to fill in a statement of arrangements so that you both know where you stand and he can't mess you or his sons about. If you want you can refuse overnights so the CSA give you more of his money - pathetic but would exert a little revenge on your part!!
As for Friday - your original plans will have to stand - you cannot at this late notice change them and do not do it now - he will think that thsi is acceptable all of the time and your time is as precious as yours - he is going to have to start dancing to your beat honey rather than you doing it the other way around!!
As for the clothes - a DVF dress over jeans looks cool and funky and not too over the top or dressy!!
