Is my friend into me? i dont know what to do?? is she a ?

i have this friend ive known for a year. we go to the mall and movies with my bf and bff. i dont know her that well. we both moved she wants to come visit me for summer. shell txt me and she'll say i miss you guys so much! but only to me. shes always trying to tell me something but then changes her mind. shes a tomboy. i dont hate gays i love my sister and her girlfriend there awesome but there not butch. i get uncomfortable around the butch s im fine being around girly ones because im a girly girl. i know im being a horrible friend ignoring her txt but im getting this vibe that she like me more than a friend she even knew me before we met. i dont want her to be alone with me in my appartment. since i live close to my ex who knew her and his family longer i suggested to him that she stay with his family there ok with it. i dont know if im being paranoid its just the way she looks at me lol. she knew my ex and best longer then me.
