She is flirting with you so badly~~~~ ^_^ She is definitely comfortable around you to flirt with you, and I think she knows you like her. Being friends for eight years will definitely give you both a good foundation because you have already done most of the work for a relationship, but you do need to be careful because if something bad happens, you will lost both a girlfriend and a friend. But I would confess to her. Tell her how you feel, tell her you just want to tell her because you want to be honest with her, and don't expect anything from her. You might be lucky. She might like you back. But don't get your hopes up. If she doesn't like you the same, then don't give up. There will be someone who will accept your heart and will treat you the way you deserve to be treated.

Woooo~ Sounds like something to meee~
