While your wife seems to be spiraling out of control, this may be good for you--and ultimately good for her as well.
You will be able to refute everything she has alleged in court where it will be public record. She will finally have to account publicly for the discrepancies between her allegations and the truth. Hopefully the court will send her a wake-up call and she'll hear it. Even if she doesn't hear it, you will be on your way to putting a home together for you and your kids.
