Crush's problem?

I followed my crush on Instagram and she followed me back immediately like 5 months ago
I decided to add her on FB but she didn't accept my friend request then so after few days I deleted it
few hours later she followed me again on Instagram lol
I didn't know what that meant till I resent a friend request few days after and she accepted it immediately 😕
what's wrong with her?
