I'm really sorry to hear about the problems you're having. You are still getting some great advice from everyone here. What JCJ said about her finding it more difficult to live together because she's not getting her own way is completely spot on in my opinion. She's beginning to get desperate because you're not doing absolutely everything she wants as soon as she wants. You'll find a lot of people on here comparing a WAW to a petulant child and in most cases it's true. As JCJ also says, she's doing a damn good job of pushing herself away. Where no person in a relationship can be completely responsible for its breakdown, I think right now it's her who's doing more damage than you. Stop kicking yourself.
While I can't agree with your decision to move out I do admire your assertiveness in telling her you intend to come back in June. The one thing I would consider doing though is going to see a solicitor to find out about the legality of this. Don't let yourself be barred from your own home. Well done on getting back in to your own bed too. It may not do anything more to help the relationship at the end of the day but it will help you to find yourself and not dance to her tune so much. Don't get me wrong though, I don't think it will hurt your relationship in any way either.
Please don't do anything rash Mark. I know sometimes it can all feel like it's too much but believe it from me and many many more men on here. It does get easier with time. You should possibly visit your GP to just have a chat through things. Also, if you can stretch to it, consider a DB coach as I've suggested before. The prices are on this site but I think it works out about £200 for 3 sessions at the current exchange rate. The time difference is 5 hours behind us.
Do you honestly believe that your wife has grounds to petition you for neglect of your kids? I think it will be a very hard thing to prove for her. She seems completely irrational now and is making all kinds of threats. The first thing you need to do is go and see a solicitor. The initial consultation is normally free.
Good luck mate.

Sometimes you have to become lost before you can find yourself.
