Well, a small victory of sorts. Of course, I cried for an hour after it was over, but I was able to talk to my kids on the phone (well, two of them. The oldest was acting like her normal self, and she didn't want to talk - she rarely talks on the phone).
My W's father even talked to me for a bit, telling me that it was all her and nothing to do with them, that they in no way whatsoever pushed her towards this. I was polite but pointed out he was paying for her lawyer. I told him expected he was doing what he thought best for his daughter, but that I really was working on improving myself and becoming a better person.
I doubt it will make any difference, and I have no idea how he will report the conversation to her if he does mention it to her.
But, d@mn it all, my second youngest is using complete sentences now.
