Hello again....
Well what a difference a day makes. As I said earlier she looked awful and had been crying whilst at her dad's. It seems he has had words and won't be funding daft legal expenses. In addition, she has booked to view a rented house next week, agreed to the Disney trip and also said that initially our youngest should only stay with her for short periods until things settle down.
Based on how things were last night I'm flabbergasted! It has made speaking with her easier that she has finally given some ground. I won't be letting my guard down as things could change back quickly, but hopefully we can move forward more amicably. I think the plan is to tell kids next weekend about the situation, then weekend after I take them to Euro Disney.
I'll try to answer specific questions now...

Yes I'm the main carer, but for all her faults she is still their mum. Honestly I would prefer more than 50:50 but am worried that I could lose out in court due to been a dad. The cost is also an issue. I'd much rather spend £000s on the kids than lawyers. It would also likely ruin any chance of a reasonable relationship between me/wife in future. We are bonded through our children and I don't want kids to be piggies in the middle of bickering parents. The toyboy does worry me, but I'm likely to have more sway with wife on kids contact with him if we are on speaking terms (to be clear I want them to have ZERO contact with him)!

Yes, she was in a crash but it was a slow speed collision with a lorry turning so no sudden head impacts. It wrecked the car and has affected her confidence, but no physical injuries.

Thanks for all the comments, they are appreciated! Our finances have been joint since we first got together. Recently I did start resenting her increase in spending (before I knew what was going on), but once I found out about the affair I told her she must set up her own account. She has done this and from 1st May we have had separate current accounts. We are both a named card holder for each other's credit cards. Currently all credit cards have zero balance. I do need to take her name off the joint current account, however, as this will become my account.
My solicitor suggested a 3/8 to 5/8 split on household costs as my take home is slightly more than hers and then go 50:50 on groceries and cleaning stuff. At this stage she hasn't given me anything but has promised to sort out early next week.
Again, thank you all for comments and feedback. I feel much better than yesterday following her evening at her dad's. Obviously I'm still gutted my marriage is ending and really worried about how our kids are going to take the news, but at least I look like I now have the opportunity to get over things and start rebuilding my life.
