I went through a period almost identical to this one with my XW. I was an @$$ - knew it because she told me so frequently. I was miserable and making her miserable. This divorce was all about MY failings.
It's all a smoke screen. She is making decisions that she thinks are best. So are you - and anything you do that runs counter to her view of how the future will go will be attacked. She is texting from a place of raw emotion, without empathy, consideration for you, or logic. Ultimately, refraining from rising to her level of hate is something for which you WILL be thankful.
In a way, I am jealous, while admiring you (although your situation does seem a bit different.) I let my wife take the kids because I was getting a good deal - and plenty of time with them. And because farking lawyers have already got enough of my money in this life. But my children no longer "live here." It's a hard pill to swallow at times.
