Does this girl like me?

alright.. theres this girl that i like, and i want to know if she likes me back. we met at this party and we were dancing together, i noticed she was looking at me and smiling but thats just me. anyway we were on facebook and had a really nice conversation that lasted pretty long. she had smilies and hearts at the end of every sentence. then i asked for her number than she gave it to me with a heart at the end and said text me anytime. also im not a loser lol, ive had girlfriends in the past for any of you who are wondering. so yeah. and i told her she looked great and she said awww so did u. i just want to know if she likes me back. and was wondering if i should ask her out. thank you (:
