Am i being paranoid and impatient about us being close freinds? give me advice please, its kinda long sorry..?

ok so me and this girl jenny used to be extremely close during summer after 8th grade and winter break last year (June 4, 2009 - January 2, 2010). We stopped talking because i told her i like her during winter break last year and i kept mentioning it because i thought she would admit that she likes me the way i like her. Also during winter break she liked our friend amy and wanted to let go of the way she feels about her cuz amy didnt/doesnt like jenny like that so she was considering going out with me but she thought about it again and said naww because she didnt wanna mess up thr relationship we have but i was so desperate to have her go out with me that wasnt thinking about how me telling her i like her alot would make her feel, and it made her feel like sh*t. But now me and her go to the same school (last year we didnt go to the same school) and i went to 2 of our home football games and she plays drums in the band so i see her at the bottom of the stands or near under the bleachers when the band is taking a break. so one time her cousin was there and she toke my hand and made me wave at jenny and jenny waved back <3 lol. then at the next game she said omg its jayden and i said omg its jenny and we laughed. i text her every other day sometimes but recently i got a facebook (yes i know im late xD) and i added her and she wrote on my wall Monday and we talked from like 7 at night to midnight. then i bought coffee for me and her Tuesday morning and we shared it <3, and today when going to my friends gym cl 2 hangout there cuz i didnt have to take my second hour mid-term, i saw her and i poked her and she hugged me and went to her cl. we didnt say anything to each other =(, but at least she hugged me =). Then today, i walked my friend natasha to her world history cl so she can take her midterm exam and while we were going up the stairs, jenny came and walked with us because she has history with natasha. So while we were walking me and jenny and natasha were talking a little bit. Then after school i texted her around 12:00 (we had early release) and she didnt answer. Then i resended the text arounf 12:50 and she answered around 1:24. Then i replied a minute later and she didint text back so i resended it around 3:22 cuz sometimes my texts dont go through but she didnt text back. So bascially i just wanna know how come we were not as close as we were before? I mean I know its going to take time before were close again like how we were before but im sooo impatient! I also wanna know how come we dont talk as much as we used? Like when i go on facebook she's talking to people I dont know and i get jealous and today she wrote that she was waiting for this gurl jackie to arrive at her house so she can pick up her cousin then she can go to menchies (the frozen yogurt store <3) and i got jealous because we dont hang out anymore and when i see her in the hallway at school, there's a huge difference when i see her and say hi and hug her than it is when i see, say hi and hug my other friends. Maybe because im soo used to not talking to her and maybe its the same for her. Also, last night on facebook i wrote "ughhh! im so confused. i feel like my heart and my head r playing tug a war and your in the middle" (i was talking about jenny and how i feel about her) and she texted me saying watz up with my status and i explained and we talked and she told me something i never expected and i told her that im here for her <3. But i still feel sad like we arent as close as were during the summer after 8th grade in 2009. Like we dont hang out like we used to, she doesnt text me like she used to before. What can i do? I mean I know its gonna take a while for our friendship to go back on track and for us to be close again but what can i do? Also what can i do to not act shy and nervous when i wanna say hi to her? Thanks for helping me. And please give me as much advise as you can that'll help me <3. I really appreciate it.
