I seems like this girl has been flirting with me, and i like her, but i dont know if shes serious or jokeflirt

OK i dunno if she really likes me, or if shes just the kinda person who gives u hugs in the hall and says awwW ilove you online or if she really is flirting. im not the most attractive kid (but im not that bad), and ive never had a gf, and i really like this girl, how do i find out if she is serisou or not. Shes really cute.
