I too am sorry for you that it has come to this. I hope you can get something sorted out through your lawyers about the house. This is one of the reasons I was strongly advising you not to move out in the first place. It's something I got advised very early on in my sitch. I'm not sure how close English law is to Scottish but I do think you still have the right to stay in the marital home. Your W may be in a slightly more precarious position if she moves out since your name is on the deeds but I don't think she'll be able to keep you out.
On a positive note, I think you're definitely sounding better in yourself. I know that it's not where you want to be in life but it's still not time to give up all hope for your marriage. After the finances, house and visitation of the children is sorted out, it will remove most of the tension from your relationship with your W. My W and I got all that sorted out very early after the separation and things are fairly comfortable between us now. There's next to no conflict. No, we're still not back together nor do I know if we ever will be but there's a lot less drama in our lives now. It gives us the chance to just get on with it and put Wee Man first. We obviously still have our differences of opinion but now all the major issues are out of the way, it's fairly easy to resolve these minor issues in a relaxed manner.
I would ask that you don't hate your W for this. You mentioned that you're starting to see her for what she is. I would disagree that she was acting like herself right now. You've backed her in to a corner and she's getting desperate. Her plans are crumbling before her. It may be exactly what she needs to get out of this fog. Let her face up to the consequences of her decisions and give the dust time to settle. You may see a very different W emerge out the other side. Like I said, don't lose all hope. There's always room for it in our lives.
Take Care
