I disagree that it's over. If it was "over," you would have been served by now.
You are in his head. The WAS textbook says that leaving is easy. The LBS begs and pleads, and is unattractively needy, and it's a cinch to leave.
That's not you.
I agree that it sucks. It's awful. But, believe me, you won the battle today. He is on his heels. Does that mean he is going to have a change of heart? Who knows. But, at the very least, you are making it very difficult for him to move forward.
Hey, we all want to be happy. And we all push away things that intrude on our enjoyment of life. Your husband is no different, so if he really believed that he can't imagine life without her in it and he doesn't want this life (with you...home/family)... he would have visited the courthouse already, and you would be posting in the "surviving" forum.
Although it may indeed be over, you owe it to yourself and to your children to be able to say that you did your very best to save your family.
