Do I ask her out or become close friends?

hey guys urm realy feelin crappy cuz I like this girl so much a little bachround is that I met because ironicly I liked her friend which coincidently meant I was introduduced to this girl. She seemed real into me unlike the girl I liked hoo seemed to just like another guy so I'm not the one for sitting crying over losing a girl so I moved on and all this girl that I'd met would do would be message me askin anything like who I liked we'd flirt we became quite close but only prob was we never saw each other which sucks cuz I feel now that I could of asked her out. So now she's become real popular were tlkn quite a bit she even clearly leaves little hints that she likes me a lol more than other guys like I get more x's on fb or I'm the one who gets the 'love you' but I dunno...is she just being friendly plus she's realy become popular more guys like her but ... I've realy fallen for her and don't wanna screw it up were hangin out soon she's bringing few of her girls and I'm bringing a friend . Do I ask her out then I realy like her is there anyway I can rly show her I like her . We always catch each other staring at eachother across the cl :) do I ask ? or do I just move on ? THANKS ALL
