Thank you so so much for the fist bumps everyone 
I really appreciate all the 'you're fantastic and amazing' comments, they give me a big smile but it's not easy to believe and I would say to anyone in this situation that 9 years ago I was anything but strong or fantastic. It has taken a long time to get here, a long time to detach and to see things really for what they are, in fact I'm not fully there yet on that front, only last month I have been having my eyes opened and realising things - I started this thread still unsure of what was happening in my marriage but sure enough that things 'weren't right' and so had booked a preliminary meeting with a solicitor.
I never, ever thought I would have the strength to finally end it. I had reached the point of sobbing hopelessly into my pillow or in the bathroom literally thousands of times, dreaming of it finally being over but then the fear of 'getting the ball rolling' and 'what the hell will I do financially' and 'what the hell will his reaction be' plus him then turning back on the charm as you have all seen brought me straight back down to the bottom of the pit again.
But, and this is a big thing to say about an anonymous forum in terms of somebody's precious and real life on this planet - if it hadn't have been for Mumsnet, all the worldy advice and experience here, the links to fantastic articles and books, the absolutely amazing support which I have really been falling back on - then I really don't think I would have got this far, I really don't.
It's been that and reaching out for support, recognition from the solicitor that I am doing the right thing, getting into the freedom programme and asking my GP for counselling. This has been where the strength inside has been building very gradually every day, this and recognising (with the help of MN!) that a wobble is just that. A wobble, and to KOKO 
That aside, H might not be coming round tonight now, so dirty pants it is for him tomorrow then
