If a shy/insecure girl acts like this to two people, who is she more likely to crush on?

[Nick]

Person A:
- In real life they don't flirt but talk about general things
- They talk on Facebook
- She occasionally likes his posts & will like his profile pics every so often
- They have each other's phone number

Person B:
- In real life they flirt (she laughs a lot, calls him petnames, doesn't flinch when they touch each other, she breathes fast etc)
- They don't talk on Facebook
- She doesn't like his profile pictures
- They don't have each other's phone number

And explain why you decided what you did. Thanks I am neither person by the way, this is just a general question about shy girls behaviour

I say she is more likely to like person A because she does not flirt with him in person because she is really shy but she wants to find a way to flirt so she turns to Facebook where she can say things she would not normally say. Person B seems like a cool person that she is comfortable around to joke with and stuff but has no desire to speak with that person after they are out of direct site.
