<human>: Give me the gist of the text in a nutshell

Warning if you couldn't tell by the title it's going to be some High school level problems. I appreciate all the help I can get. 

Background: so this girl has had  a crush on me since she was in sixth grade, honestly I never thought anything about it cause she was two years younger than me. Anyways this year we actually got pretty close.  She is actually the first girl I ever told I liked. Anyways we talked about it (this is all about a month and a half ago) and she said she wasn't ready for another relationship cause of how her last one ended (it was pretty shitty). Anyways she said she still did like me and we texted for a while. Anyways for the past three weeks we haven't texted. Then I thought she moved on from it. My sister who is a close friend of hers keeps telling me she still has a huge crush in me. My friends say it's just my sister enabling me.  Anyways the other day she texted me to wish me a happy birthday and we started texting. I want to text her again but Im honestly lost what to talk about. I honestly have no clue what to do with anything. It's sucked cause I can't get over her. 

I can expand on anything and I'll answer any questions cause this is pretty much a one use account so I don't have any personal information on it.
<bot>: a month after I told a girl I like her things kind of faded. I still have feelings for her and apparently she still has feelings for me and now I'm unsure  to do next
