Did i mest up with her?

theres this girl that i been talking too, well to make the story short last night we were talking and she kept on saying that she has a secret that she wants to tell me, that she really feels like she wants to tell me but that she cant because she wants to wait till im hers (saying when we are going out) she kept on bringing the whole secret thing and saying that she wants to tell me so bad but that she coulnt yet. She made it so obvious of what it was. She want it to tell me that she loves me. She even told me she didn't want to tell me yet because she don't want to be rejected or she didn't want it to be weird or something. Well i guess she couldn't hold it no more and she end it up telling me that she loves me. I said it back because i kind of felt the same way. Then before we hung up after we said good night to each other and all that stuff i told her that i love her, then she said that she loves me too. She had told me that she was going to call me today around 11am. Every time she tells me she going to call me at a certain time she never fells, but now today after the whole thing that happen last night she still haven't call me yet. We aren't dating yet, but was it a mistake or not that i told her that i love her before we hung up?
