Hi Blue,
She seems to enjoy the attention.
When she isn’t getting it from you, she tends to respond by ignoring you as well. However, when you give her attention, she tends to enjoy it.
It may only be about the attention though.
She hasn’t really gone out of her way to show you that she has had a change of heart and would like to go out with you.
You have already asked her out in the past and she rejected you.
Hence, it may not be a good idea to ask her out again. If she truly likes you, the onus is on her to make a move, not on you.
