A girl I like said "we should be friends first and then see" when I confessed but she's not looking for a relationship, what does that mean?

I didn't know her too well when I confessed to her, and she told me that. There's been a day where she was really close and wanting to hug me, but these days it's back to normal. It's really confusing but her friends say she's picky. We have hanged out before and it's been pretty good and making slow progress, but recently she's said she's still trying to figure out her feelings. What direction am I headed towards to?
