i really don’t know what kind of help you are asking for exactly. from what you said, all indications point to her liking/loving you. why do you feel things have changed? what makes you think her feelings have changed?
i’ve never chatted on facebook, but i’m assuming you can chat with different people at the same time. maybe the reason she doesn’t answer you immediately is because she is having conversations with other people as well as you.
i think you need to slack off a bit. just let things happen at their own pace and don’t rush things or pressure her anymore than you already are.
it seems to me you’ve continually asked the same question and she consistently gives you the same answer.
