Thanks for the reply Brian, I'm on my phone so will make this brief.
I don't think I explained it very well, in her mind at the beginning she said it was all my fault, I have never personally accepted anything above 70/30 my fault and now after 7 weeks have passed I won't accept anything higher than 60/40. After 1 of our discussions before I moved out the second time I fought hard (know not to do that now) to get her to accept some responsibility and she said she did but I'm not sure how genuine that was and wether it was just lip service. The 'can't do anything right' was simply my observation from her that she points out the tiniest little thing I do wrong (in her eyes) because she is so ultra negative and pessimistic at the moment and looking for everything she can to catch me out. I guess she is trying to justify how she feels at the moment - hadnt thought of that till just now!

I know she has other issues. Loads of issues from her childhood where she felt controlled and beaten by her father and she felt she was always singled out by him not her brothers or sister. I know through my perception I am reminding her of her father at the moment a lot, when I gave her the ultimatum about nick or me, when I had calmed down a bit she said she was scared of me, she's never been scared of me before, in fact she's the dominant scary one. I worked it out a few weeks later that she was seeing her father not me. Many times in the MLC boards it is said that MLCers see their spouse as their parent and tied in with her teenage behaviour at that time it makes complete sense.

Thankyou for the other kinds words, I knew all that but it means so much more when it's said personally to me, so thankyou again for taking the time and trouble to write it out.
