Well, this happened a couple months ago, but she found out that her step-dad got this other lady pregnant after him and her mom split up. And now he's trying to get back into their lives so that might be it. Other than that, the only big thing that I can think of right now was that she turned 18 and she keeps on telling me that because of that she feels so free because she can move out anytime she wants now, so she doesn't really need her moms permission any more, plus she's about to graduate from HS. Basically, I think she feels like an adult finally. That might be it too.
