Girlfriend says she is confused, doesn't know what she wants or wants to do. What does this mean?

I've been dating this girl for a little more than 4 months, she is one 30 and we had been taking things very slow from the beginning. However in the last month things started picking up and we were spending more time together. Then she all of a sudden started being more distant. Some days she would feel really warm and some days she would feel distant. The other day we were chatting over text messages and she says she's not sure what she wants. Also she does have a lot going on lately, she's moving into her new place, she's applied for a new position at work. She is very emotional about leaving her parents for the first time and I think it may be a bit overwhelming for her. I haven't messaged or talked to her the last 2 days since our little chat. Thought a little space maybe good but am just not sure. I really like her but she seems to confused or is she trying to put me down nicely?
