Can you get the mentality and thoughts of this user , I am so confused?

So a female user sent me a text dm , and talked very nicely and politely and she told me she wants talk on fb , and she gave me her fb link , and suddenly she blocked me even I didn't said anything besides just answering her nicely.
I couldn't get her behaviour
Can anyone understand why do someone do that?
