Does this girl like me? (Girls)?

Ok so after p.e and after I got changed back into my school clothes I walked up to her group of friends and she said ''hey!'' Im like ''hey'' then she said ''Can I have a hug?'' btw I dont hang with this girl we just talk a little during homeroom, and when she see's me (almost every time) she says my name like really happily, anyways im like ''sure'' so we did and believe it or not it is the first time I hugged an actual girl I kind of liked. so does she? p.s. sometimes at lunch I catch her starring at me.
