I'm a girl who likes the girl who likes me ... Help ?

I like this girl ... I met her almost a month ago now and I've liked her since the day I met her . Her and I have started getting into a friendship and last weekish I admitted I liked her and she admitted she liked me . Her ex is friends with my best friend and her ex is telling my best friend EVERYTHING bad about her . My crush slept over last night and we watched Dirty Dancing and Grease last night because we got bored . She's 14 and I'm 13 and she posted as her fb status 'I'm at my crushes house and all I want are cuddles' so I went and cuddled with her .I really like her and last night we ended up holding hands a lot . When I went to put duct tape on my mouth to stay quiet and to stop talking to the Tv she ended up playfully wrestling with me to get it off my mouth and the she kissed my cheek and fore head . Her and I flirt a lot and I think I REALLY like her and she really likes me back (Or she said) but I just have no idea what to do because my friends and family kept telling me last night to kiss her or ask her out and I didn't because I'm not ready to date her ... So I'm not sure what to do ... Help me and explain to me why I even feel like this ... Please .
