Confused with her way of communication/interaction

Theres this girl I like, we were friends, i believe we still are friends, yet she's everything to me. I expressed my love for her maybe a little too early about a year ago, then, I never heard back from her. A year later, about a month ago, I sent her a message to let her go and close the book and moved on in a nice way. But after a few weeks I saw her again at a party. We talked all night, and it was really good to see her again. She was a little uncomfortable at first but we quickly hit it of well. At the end of the party we said "see you later" to each other and it was all well.

The next day (recently) I sent her a message and how great it was to see her again and what a surprise it was, she's that type of person that likes the surprise/unexpected element if you understand what I mean.

But now she does not speak to me again. I recall her saying something like "You don't have to reply to someone" in a general conversation with her, and i agreed. It's almost as though she wants me to communicate with her, but she'll only talk to me when it suites her...

Is this normal? And what does it mean? Is this one of those weird girl behavioural things that confuses us guys? Because im surely confused, I dont know who I am to her, anymore. A friend or not? A potential lover or not?

This is really confusing me.

awww , well this is a touching story . luckily , I know whats goin on here . she was scared when you told her that you loved her , so when she stopped talking to you , she probably came up with some sort of plan for when she talks to you again . so i'm 99.99 % sure she's just playing hard to get . but if you really dont know what's going on between you guys , just give her a call and be completely open and honest . just say , " I know we havent talked for a while but I just really need to know if we're friends or not friends or what ?" hopefully she wont hang out . she might even be impressed by being so frank .

but if you're confused about girls making these types of plans , its really so that we dont get hurt . I personally dont like them because they're really confusing and im not the kind of person who would do that . anyways , maybe when you told her you loved her , she didnt talk to you and she created this plan because she didnt know if she actually loves you . or if she actually has feelings for you . and she maybe just didnt want to get hurt like most girls .

if you get into a relationship with her again , or something close , just remember to take it slow and let her know that you're there for her and that you won't hurt her (assuming you're that type of guy) .

Good Luck ! :D
