Heather, I'm sorry, but it sounds like he's still looking to you to help him. The internet is a great way to locate jobs and he can do this on his own w/o your help. Heck, you are looking for a better job yourself.
Sounds to me he's finally coming to terms w/the fact that you are moving on w/your life and the grass on your side of the fence appears to be getting greener by the day for him.
Maybe he wants to move closer to have more interaction w/your daughter or maybe he's hoping that you'll take him back w/o doing the hard, necessary work. I wouldn't be a bit surprised if things aren't going well where he's at right now. Not your problem.
Keep the focus on you and your daughter. You've had to fight tooth and nail to get where you are today w/o his help. Allow him to figure things out for himself. He truly needs to grow up.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
