If she likes me why does she take so long to reply?

There is this stranger we live in different states. I added her on Facebook randomly. After liking a few of her pics she inboxed me and we hit it off. She is asking me lots of questions about myself and there was a bit of flirting going on. She said she wants to get to know me better and that I intrigue her. However she did mention she's not co-dependant like her friends. I respond to her and it remains unseen and unreplied to until days later. I know she is busy. Should I just not bother? Should I take just as long to reply?
