Hi everyone! One way back from an Oxford-Hertfordshire round trip via London by public transport. It has not, to put it mildly, been easy but am on the home leg now!
Thanks, Pink, I'm feeling slightly more human today and at least my brain is working in between sneezing and such! I fully intend to be rid of this cold within 48 hrs! 
I'm still chuckling at your surprise little-girl-baby! You'll find a name soon enough - no rush! Are you and Tramp going to same physio?! How cool is that!
Stealth, have been thinking of you today. Well done on reaching your decision re amnio. Hmm, mewonders whether DH playing iPhone game is a form of denial/processing on his part? Men are wired so differently with regard to some things, and really annoyingly at times 
. Will be thinking of you even more tomorrow. How long do you need to wait for the test results?
Keep going, JoJo! 500 words is good! I always speed up towards a deadline anyway. I also use a trick which involves me kidding myself that I am writing or chatting to a mate. I end up with a load of ramble, but it covers all the ground necessary so you have the bare bones to refine. Helps to break the task down loads. Oh god, re scar. Yikes. Yikes! OWWW!!! The thought of it makes my knees go funny. I was worried about my 15-years old 12-inch scar from belly to public bone but, it's so damn old it's doing fine. I am really not helping, I know, but poor you! Youch! See a chemist/nurse re some cream, I reckon. You don't want an infection.
Uh-oh re double trouble, Zoey! Crib looks lovely, by the way! Though I'm trying not to think about your scar too! Puts my own little gripes into perspective. Hope it gets better soon Date night! 
He's a good 'un! My DH is amazing in a squillion lovely and brilliant ways but initiative does not feature highly in his list of top attributes! Have a great night!
Hermione yay about the doppler! Pleased for you!
Gummi - brilliant!!
Possom - hope yours tomorrow goes well!
Welcome back, MrsRigby, although I'm sorry that you're so desperately unhappy. It seems to me you need to move away from the blame game and decide, fundamentally, whether you want to be in this marriage or not.
a) If yes, then you need to call time on all this crap and get yourselves into couples therapy. This may mean acknowledging the part you play in the dynamic between your DH and yourself - not easy, I know.
b) If no, then you need to get a solicitor, get a divorce, and find some peace and happiness in a new life. I put in 1% deposit into our house and DH 99% tho I contribute equally to mortgage, mortgage overpayments, and bills. I'm a worst case scenario planner so I've sought advice as to where this leaves me if we were to split and actually, in marriage, it seems that his and her assets are actually joint assets. Especially if you have kids. You are not as badly off as you think. So, if you want to get out you can.
Either way I suspect your children will be happier as this stress between you both will, I can assure you, be leaving it's mark on them. They may be able to devise coping strategies for it now but in the future this absorbed stress may come back to haunt them. (I'm speaking from experience - every adult in my childhood was deeply unhappy and angry with each other about it. I was a dysfunctional young adult and it took me years of counselling to straighten myself out a bit. And I'm by far an uncomplicated human being even now.) If you need any spur to help you take some steps to make your life more happy then achieving some clarity of thought about your childrens' wellbeing will do it?
There is plenty of specific advice on other threads. You're not alone on MN, but from the way you put things I get a strong sense that you do need to take more active responsibility for the quality of your and your childrens' lives. Sorry to be tough! I know it's not as easy as it sounds, but you come across as being at or near breaking point.
