There is still something wrong

I do not know what, but there is something wrong.
I noticed she was a little bit enthusiasted, but two days ago I asked her if she wants me to write or not, received strange answer: "You can write me if you want".
That was a litle bit rude of her. That means: "Do wat you want - I don't care".

What else could I do, as to settle a condition: "I will write only if you want me to", and offered her e-mail exchange as a part of a tiny step forward.
I get the confession: "I don feel so enthusiasted as on the begining..."

Pity, sorrow, predictable.
