You won a major victory for yourself this week. The judge didn't see you as a bad father. I can imagine how pissed your W is that things didn't go her way.
Now's the time to make a stand. Yes, I know you feel a little helpless for not having a job. You have been actively looking for on and I hope will continue to do so. You were awarded some monetary support. It is your duty as a father to make sure she follows the court order so you can take care of your kids. She isn't doing it. Get you L involved, whatever you have to do.
I know you're stuck and don't take this the wrong way. This isn't the time to be nice or anything like that. Hound her about it. Make her sick of you asking about it. Do not let her get away with this. Definitely get your L involved right now.
Do not wait!
And, as always, take care of yourself and your kids. They know who is taking care of them and loving them. It sure ain't mom, and that's a shame. Love them enough for both of you.
